|
|
|
|
* A copy of javah (to produce C header files from Java source code)
|
|
is now required to generate the files in include.
|
|
* The javac check has been changed so that it attempts to find ecj,
|
|
javac and gcj (in that order). You may override this by using
|
|
JAVAC=<preferred javac>
|
|
|
|
Runtime interface changes:
|
|
|
|
* Removed VMFloat.floatToIntBits amd VMDouble.doubleToLongBits.
|
|
* Added new getParameterAnnotations() methods in Constructor and Method.
|
|
|

|
|
|
|
* Small compile, configure and build fixes.
|
|
|
|
New in release 0.96 (Oct 15, 2007)
|
|
|
|
* New experimental GStreamer javax.sound peer (see README.gstreamer)
|
|
* The JNI interface has been updated to 1.6
|
|
* Better support for the OpenJDK javac compiler

|
|
* Much improved Escher AWT peers
|
|
* Many bug fixes including improvements to AWT and Swing support
|
|
|
|
Runtime interface changes:
|
|
|
|
* Add VMFloat.toString(float) and VMFloat.parseFloat(String). Default
|
|
implementations are the same as previous behavior.
|
|
* Add new default implementations of VMMemoryMXBean.getHeapUsage()
|
|
and VMMemoryMXBean.getNonHeapUsage() via iteration over the memory
|
|
pools of the appropriate type.
|
|
|
|
New in release 0.95 (Apr 23, 2007)
|
|
|
|
* Full merge of 1.5 generics work.
|
|
* Added 1.6 java.util.ServiceLoader support.
|
|
* The ASM library is now included. A separate copy is no longer
|
|
needed. gjavah works out of the box now.
|
|
* The setReadTimeout and getReadTimeout methods have been added to
|
|
java.net.URLConnection. They are now fully implemented for http URLs.
|
|
* The java.lang.management implementation now includes the new features
|
|
added in 1.6
|
|
* java.util.TimeZone now reads time zone information from the system
|
|
zoneinfo files (see also runtime interface changes below).
|
|
* The collection classes have been updated to support all the 1.6
|
|
additions.
|
|
* java.util.spi 1.6 package has been added and is used in java.text.
|
|
* Bootstrappable with OpenJDK javac compiler
|
|
(use configure --with-javac).
|
|
* Large speedups (and locking behaviour updated) in Graphics2D cairo
|
|
and freetype support.
|
|
* Better detection of browser plugin mechanism for mozilla, iceweasel,
|
|
firefox on various platforms.
|
|
* Inclusion of generic javadoc classes in tools.zip to support more
|
|
javadoc processing tools.
|
|
* Added documentation for command lines options for the included GNU
|
|
Classpath Tools gjar, gjavah, gnative2ascii, gorbd, grmid,
|
|
grmiregistry, gserialver and gtnameserv.
|
|
|
|
Runtime interface changes:
|
|
|
|
* gnu.java.lang.management.VMThreadMXBeanImpl has gained three new
|
|
optional native methods to allow the 1.6 version of the threading
|
|
bean to be supported. One (getMonitorInfo) fills in information
|
|
about object monitor locks held by a thread and is only required
|
|
if the monitoring of object monitor locks is supported by the VM.
|
|
The other two (findDeadlockedThreads and getLockInfo) are related
|
|
to ownable synchronizers (part of the java.util.concurrent suite)
|
|
and only required if monitoring of locks relating to these is
|
|
supported by the VM.
|
|
* java.util.VMTimeZone and java.util.TimeZone have been refactored
|
|
to simplify the reference implementation. VMTimeZone.readtzFile()
|
|
and VMTimeZone.skipFully() have been removed, and a new method
|
|
VMTimeZone.readSysconfigClockFile() has been introduced.
|
|
* VMs need to set the system property "gnu.java.util.zoneinfo.dir"
|
|
to point to the directory where zoneinfo files live. In libgcj
|
|
this is set to the value of the TZDATA environment variable, or
|
|
"/usr/share/zoneinfo" if this is not set.
|
|
* VMFile has been extended to support new 1.6 methods (canExecute,
|
|
setReadable, setWritable, setExecutable).
|
|
|
|
New in release 0.93 (Dec 8, 2006)
|
|
|
|
* CORBA objects that exist on the same virtual machine and only are connected
|
|
to another ORB are now accessed directly and no longer via network. It is
|
|
the same feature that RMI implementation provides. These faster calls should
|
|
be completely transparent, as the parameters are cloned, where required.
|
|
Currently the direct calls are only possible for the non-deprecated objects
|
|
that are connected to the ORB via POA.
|
|
* The 'javah' tool has been added. It requires the ASM library
|
|
(see asm.objectweb.org); it can be enabled with the --with-asm
|
|
option to configure
|
|
* Added the rmi and corbaname URL context factories for JNDI.
|
|
* Fixes in the JNDI InitialContext now allows to plug-in user implementation.
|
|
* Removed currentClassLoader method from
|
|
vm/reference/java/io/ObjectInputStream.java.
|
|
* Added firstNonNullClassLoader method to
|
|
vm/reference/gnu/classpath/VMStackWalker.java. VMs are encouraged to
|
|
provide a more efficient implementation.
|
|
* Added aton method to vm/reference/java/net/VMInetAddress.java.
|
|
* NetworkInterface has been implemented for systems that provide the
|
|
`getifaddrs' function.
|
|
* java.nio.channels.Selector implementations have been added that use
|
|
the kqueue notification mechanism on Mac OS X and *BSD, and that use
|
|
the epoll notification mechanism on Linux 2.6.
|
|
* java.nio has been refactored to support more non-blocking operations
|
|
natively. Blocking IO classes have been refactored to call
|
|
non-blocking classes. Non-blocking accepts, connects, and
|
|
scatter-gather IO should now be better supported.
|
|
* HTML support for Swing has been greatly enhanced.
|
|
|
|
Runtime interface changes:
|
|
|
|
* java.net.VMNetworkInterface and java.net.NetworkInterface have been
|
|
updated to keep native-modified state in the former, and to simplify
|
|
the native code in our reference implementation.
|
|
* gnu.java.nio.VMChannel has been expanded to better support native
|
|
non-blocking IO. Most native state data (such as file descriptor
|
|
integers) has been abstracted away into private state in the runtime
|
|
interface.
|
|
* gnu.java.nio.VMPipe has been similarly changed.
|
|
* gnu.java.net.VMPlainSocketImpl has been changed to remove some
|
|
functionality now provided by VMChannel; datagram socket-specific
|
|
methods have also been moved here, deprecating VMPlainDatagramSocketImpl.
|
|
* gnu.java.net.VMPlainDatagramSocketImpl removed.
|
|
|
|
New in release 0.92 (Aug 9, 2006)
|
|
|
|
* GConf is used as a backend for java.util.prefs. GNU Classpath
|
|
thanks to Mario Torre for this contribution!
|
|
* libjawtgnu.so has been renamed libjawt.so for binary compatibility.
|
|
libjawt.so should be installed in a VM-specific directory rather
|
|
than directly in /usr/lib. Proprietary VMs put their libjawt.so
|
|
implementations in VM-specific directories but search /usr/lib first.
|
|
If GNU Classpath's libjawt.so is installed in /usr/lib it will create
|
|
problems for people who use a proprietary VM to run AWT Native
|
|
Interface applications.
|
|
* The GdkGraphics2D backend has been made the default. There is no
|
|
longer an explicit dependency on Cairo, the --enable-gtk-cairo
|
|
configure option is gone, and GTK 2.8 or higher is now required to
|
|
build the GTK peers.
|
|
* A Mozilla plugin, 'gcjwebplugin', is now included. It introduces a
|
|
dependency on the Mozilla plugin support headers and libraries.
|
|
* New java implementations of png and gif imageio readers and writers.
|
|
* A tools.texinfo document has been created and now includes
|
|
documentation about:
|
|
* appletviewer
|
|
* gcjwebplugin
|
|
* jarsigner
|
|
* keytool
|
|
* Several new tools are now included:
|
|
* appletviewer
|
|
* jar
|
|
* native2ascii
|
|
* serialver
|
|
* keytool
|
|
* jarsigner
|
|
A new configure option --enable-tool-wrappers causes wrapper
|
|
binaries to be built for VMs that support the JNI Invocation API.
|
|
* We've imported the JSR 166 (concurrency) reference implementation.
|
|
* javax.sound.midi providers have been added to read and
|
|
write standard MIDI files.
|
|
* A javax.sound.sampled .au and .wav file readers have been added.
|
|
* New Java Virtual Machine Tool Interface header, jvmti.h.
|
|
* AWT peers for X Windows based on Escher (a pure java X protocol
|
|
implementation) have been added. So far it supports AWT 1.1 style
|
|
Graphics, image loading via ImageIO (PNG, GIF and BMP images in this
|
|
release), top level components as well as mouse and keyboard input.
|
|
It is capable of running many Swing applications. Graphics2D and
|
|
AWT widgets are not yet supported with this peer set.
|
|
* GConf based util.peers backend (see the --enable-gconf-peer and
|
|
--enable-default-preferences-peer configure options).
|
|
* Support for batch importing trusted certificates for use with ssl
|
|
connections (see script/import-cacerts.sh).
|
|
* NIO scatter-gather channel support.
|
|
|
|
Runtime interface changes:
|
|
|
|
* A new class, VMURLConnection, is used to implement
|
|
URLConnection.guessContentTypeFromStream. The reference
|
|
implementation uses libmagic (and falls back to doing nothing if
|
|
libmagic is not available).
|
|
* The method gnu.java.io.PlatformHelper.toCanonicalForm() has been
|
|
replaced with a JNI implementation of VMFile.toCanonicalForm() for
|
|
GNU/Posix systems.
|
|
* A new class, VMRuntimeMXBeanImpl, is used to implement
|
|
the low-level support of the runtime management bean.
|
|
VMs should use it to supply the input arguments and start
|
|
time of the VM. In addition, one of sun.boot.class.path
|
|
or java.boot.class.path should be defined by the VM to
|
|
support the optional boot class path access functionality.
|
|
* The Unsafe class was moved back to the place expected by the JSR 166
|
|
reference implementation. We've also added a couple other new VM
|
|
classes to support the JSR 166 code -- sun.reflect.Reflection and
|
|
sun.reflect.misc.ReflectUtil.
|
|
* Another new class, VMClassLoadingMXBeanImpl, is used to implement
|
|
the low-level support of the class loading management bean.
|
|
VMs need to supply it with information about how many classes
|
|
are currently loaded, how many have been unloaded and whether
|
|
verbose class loading output is on or off. Provision should also
|
|
be made for the latter to be toggled at runtime.
|
|
* VMThreadMXBeanImpl is used to implement the low-level support
|
|
of the thread management bean. Providing this interface requires
|
|
providing a fair amount of information about threads, including
|
|
optional time and contention monitoring, and instances of the
|
|
new ThreadInfo class in java.lang.management. getState() has also
|
|
been added to the VMThread interface; this is required by the bean
|
|
as well as java.lang.Thread.
|
|
* VMMemoryMXBeanImpl is used to implement the low-level support
|
|
of the memory management bean. Providing this interface requires
|
|
providing information about the levels of heap and non-heap memory,
|
|
and the number of objects eligible for garbage collection.
|
|
* VMCompilationMXBeanImpl is used to allow for optional compilation
|
|
time support for Just-In-Time compilers.
|
|
* VMMemoryPoolMXBeanImpl is used to implement the low-level support
|
|
of the memory pool beans. Providing this interface requires
|
|
providing memory usage statistics for each supported bean.
|
|
* VMManagementFactory provides the names of the memory pools,
|
|
memory managers and garbage collectors maintained by the virtual
|
|
machine. These are used to create the beans by the ManagementFactory.
|
|
* VMMemoryManagerMXBeanImpl and VMGarbageCollectorMXBeanImpl provide
|
|
low-level support for memory managers (including the specific subclass
|
|
of garbage collecting memory managers). The interfaces for these
|
|
require no more than enumerating the number of collections and the
|
|
time spent (for garbage collectors) and a relationship to the memory
|
|
pools (for all), along with a validity check.
|
|
|
|
New in release 0.91 (May 15, 2006)
|
|
|
|
* Experimental activation (java.rmi.activation) support, including RMI
|
|
activation daemon and persistent naming service tools.
|
|
* Experimental printing support: The API implementation of the javax.print
|
|
packages has been finished and work on the printing provider implementation
|
|
started. Currently supported features from the Java Print Service API are
|
|
print service discovery (CUPS registered printers), single document print
|
|
jobs and support for client-formatted print data. An example application
|
|
(see: examples/gnu/classpath/examples/print/Demo) has been added to show
|
|
the API usage for service discovery and printing of files.
|
|
* The GTKToolkit now gives access to the both the system clipboard and
|
|
system selection.
|
|
* Custom mouse cursor support has been added to the gtk+ peers. And cursors
|
|
can now also be set on light-weight components.
|
|
* Free Swing improvements: Support for OceanTheme has been mostly completed
|
|
and turned on as default Metal theme. X11-style Copy and Paste behavior in
|
|
text components with the middle mouse button. Support cursor changes on
|
|
various components when resizing. Support for Look and Feel window
|
|
decorations has been added.
|
|
* Updated locale data information to CLDR 1.3.
|
|
* Various bugs in Classpath's SecureRandom implementations have been
|
|
fixed; that class now respects the "securerandom.source" security
|
|
property and the "java.security.egd" system property.
|
|
* Support for assistive technologies has been added to AWT and Swing.
|
|
|
|
Runtime interface changes:
|
|
|
|
* A new class, VMArray, is now available which separates the native
|
|
array creation method from java.lang.reflect.Array.
|
|
* A new class, gnu.classpath.Unsafe, is provided for handling the
|
|
new low-level operations required by java.util.concurrent.
|
|
* The reference implementations of Method, Constructor, and Field
|
|
now have a new native getModifiersInternal() method. The public
|
|
getModifiers() method in each case has been rewritten in terms of
|
|
this method.
|
|
* The reference implementation of VMThread has been updated to handle
|
|
the new Thread.UncaughtExceptionHandler support.
|
|
* A new class, java.security.VMSecureRandom, is now available that is
|
|
used to generate random numbers for seeding cryptographically-secure
|
|
pseudo-random number generators.
|
|
* VMClass and the reference implementations of Method, Constructor and Field
|
|
now include a number of 1.5 methods imported from the generics branch.
|
|
These are all optional (in the sense that the methods associated with them
|
|
merely fail on use if the VM doesn't provide them, rather than the
|
|
VM failing altogether), but VMs should aim to support them where possible.
|
|
* The implementation of java.lang.instrument has been merged to the main
|
|
branch from the generics branch.
|
|
* The VM interfaces of the main branch and the generics branch are now
|
|
consistent with one another. As a result, the main branch includes an
|
|
additional environ() function in VMSystem and an additional argument has
|
|
been added to nativeSpawn() in VMProcess.
|
|
* Annotation support is now available in the main branch, if the VM supports
|
|
it. The VM should implement VMClass.getDeclaredAnnotations,
|
|
Constructor.getAnnotation, Constructor.getDeclaredAnnotations,
|
|
Field.getAnnotation, Field.getDeclaredAnnotations, Method.getAnnotation and
|
|
Method.getDeclaredAnnotations.
|
|
* java.lang.Package now has a new constructor that takes the defining
|
|
ClassLoader as an extra argument. If you use a custom version of
|
|
VMClassLoader, please switch it to use this constructor.
|
|
* The reference implementation of VMClassLoader.getBootPackages() now
|
|
reads the META-INF/INDEX.LIST resource using the java.boot.class.path
|
|
system property.
|
|
|
|
New in release 0.90 (March 6, 2006)
|
|
|
|
* Free Swing improvements: JTable columns are rearrangeable and
|
|
resizeable with mouse. Painting and scrolling are now much
|
|
faster. Plain text components now support highlighting and
|
|
copy+paste to the system clipboard. Support for styled text has been
|
|
improved, including some very basic HTML support. JFileChooser is
|
|
now usable. Global event dispatching has been implemented. Memory
|
|
consumption of Swing components has been reduced. Lots of general
|
|
bugfixes. Added new system property to turn off Graphics2D use in
|
|
Swing, even if Graphics2D is available: gnu.javax.swing.noGraphics2D
|
|
|
|
* AWT. Improved support for mixing "lightweight" and "heavyweight"
|
|
Components in Containers. Better support for dynamically updated
|
|
menus. Better 1.0 event model support for Scrollbars. Better class
|
|
documentation of gtk+ awt peers.
|
|
|
|
* GNU Crypto and Jessie have been merged into GNU Classpath; this
|
|
provides Classpath with a wide array of cryptographic algorithms
|
|
(ciphers, message digests, etc.) and implementations of SSL version
|
|
3 and TLS version 1. These roughly complement the public
|
|
`java.security.' `javax.crypto,' and `javax.net.ssl' packages, and
|
|
are service providers implementing the underlying algorithms.
|
|
|
|
* Updated HTTP and FTP URLConnection protocol handlers. HTTPS support
|
|
out of the box.
|
|
|
|
* Unicode 4.0.0 is supported. Character now includes support for using
|
|
ether a char or an int to identify code points.
|
|
|
|
* More correct handling of Object methods and serialization support
|
|
for Proxy and abstract classes.
|
|
|
|
* The new folder tools includes GIOP and RMI stub and tie source code
|
|
generators, IOR parser and both transient and persistent GIOP naming
|
|
services.
|
|
|
|
* Added experimental support for dynamic creation of the RMI stubs
|
|
using proxy classes. The rmic compiler is no longer required (unless
|
|
for research and specific stubs).
|
|
|
|
* XML validaton support for RELAX NG and W3C XML schema namespace
|
|
URIs. RELAX NG pluggable XML schema datatype library API and an
|
|
implementation for XML Schema Datatypes
|
|
(http://www.w3.org/TR/xmlschema-2/).
|
|
|
|
* Updated StAX implementaton to be compatible with final JSWDP 2.0.
|
|
|
|
* The default back end for java.util.prefs has been changed. The new
|
|
default is capable of saving and restoring preferences to and from
|
|
the file system.
|
|
|
|
* javax.imageio.plugins.bmp implementation.
|
|
|
|
* Added --enable-collections configure option which builds
|
|
"collections.jar", a 1.1 VM compatibility jar.
|
|
|
|
* gnu.regexp updated from GNU/Posix syntax to support util.regex
|
|
syntax including various Unicode blocks, categories and properties.
|
|
|
|
Runtime interface changes:
|
|
|
|
* A new class, VMMath, is now available which separates the native
|
|
mathematical functions from java.lang.Math. The previous fdlibm
|
|
implementation now forms the reference material for this class.
|
|
|
|
* Updated VMObjectInputStream class to return Thread context class
|
|
loader if no other class loader is found.
|
|
|
|
* Updated documentation on InstrumentationImpl in vmintegration guide.
|
|
|
|
New in release 0.20 (Jan 13, 2006)
|
|
|
|
* New StAX pull parser and SAX-over-StAX driver. Lots of DOM, SAX/StAX,
|
|
XPath and XSLT improvements. Support for XInclude and XML Base added.
|
|
Conformance is now regularly tested against various test-suites at
|
|
http://builder.classpath.org/xml/ See also doc/README.jaxp.
|
|
|
|
* Full beans XMLEncoder implementation.
|
|
|
|
* javax.sound.sampled implementation.
|
|
|
|
* javax.print.attribute and javax.print.event implementated.
|
|
|
|
* Lots of new datatransfer, print swing and swing.text work and optimization.
|
|
|
|
* Additional 1.5 support. Including new (separate) generic branch release.
|
|
|
|
* SecurityManager cleanups and start of review of all Permission checks
|
|
(includes adding lots of new checks to the Mauve test-suite).
|
|
|
|

* New method VMStackWalker.getClassLoader() was added to avoid an infinite
|
|
loop between getCallingClassLoader() and Class.getClassLoader().
|
|
|
|
* The included fdlibm implementation has seen several cleanups to handle
|
|
new architectures and namespacing issues (in particular for ppc, darwin
|
|
and non-C99 compilers). Please double check any arithmetic test against
|
|
new platforms/runtimes.
|
|
|
|
* The gnu.java.net.Plain[Datagram]Socket implementations have been
|
|
turned into VM reference classes with JNI/Posix implementations.
|
|
|
|
New in release 0.19 (Nov 2, 2005)
|
|
|
|
* The Swing RepaintManager has been reworked for more efficient painting,
|
|
especially for large GUIs.
|
|
|
|
* The Swing layout manager OverlayLayout has been implemented, the BoxLayout
|
|
has been rewritten to make use of the SizeRequirements utility class and
|
|
caching for more efficient layout.
|
|
|
|
* Improved accessibility support for Swing.
|
|
|
|
* The java.net.HttpURLConnection implementation no longer buffers the
|
|
entire response body in memory. This means that response bodies
|
|
larger than available memory can now be handled.
|
|
|
|
* The Andrew Watson, Vice President and Technical Director of the Object
|
|
Management Group, has officially assigned us 20 bit Vendor Minor Code Id:
|
|
0x47430 ("GC") that will mark remote Classpath - specific system exceptions.
|
|
Obtaining the VMCID means that GNU Classpath now is a recogniseable type of
|
|
node in a highly interoperable CORBA world.
|
|
|
|
* Classpath now includes the first working draft to support the RMI over
|
|
IIOP protocol. The current implementation is capable for remote invocations,
|
|
transferring various Serializables and Externalizables via RMI-IIOP protocol.
|
|
It can flatten graphs and, at least for the simple cases, is interoperable
|
|
with Sun's jdk 1.5.
|
|
|
|
* Qt4 configury switches for OS-X. Additional to the --enable-qt-peer, OS-X
|
|
users with a Qt4 installation can build the qt-peers with the argument
|
|
--with-qt4dir=<Qt4-installation-dir>.
|
|
|
|
* Significant progress has been made in the implementation of the
|
|
javax.swing.plaf.metal.* package, with most UI delegates in a working state
|
|
now. Please test this with your own applications and provide feedback that
|
|
will help us to improve this package.
|
|
|
|
* The GUI demo (gnu.classpath.examples.swing.Demo) has been extended to
|
|
highlight various features in our free-swing implementation. And includes
|
|
a look and feel switcher (Metal default, Ocean or GNU).
|
|
|
|
Runtime interface changes:
|
|
|
|
* Changed implementation of VMClassLoader.getPackage(s) : new method
|
|
VMClassLoader.getBootPackages should be implemented by the vm, and sould
|
|
return a string array of boot package names ("java.lang", "java.net", ...).
|
|
Feedback from vm implementors for usability and relevance of the
|
|
getBootPackages method would be greatly appreciated.
|
|
|
|
New in release 0.18 (Sep 6, 2005)
|
|
|
|
* GNU JAWT implementation, the AWT Native Interface, which allows direct
|
|
access to native screen resources from within a Canvas's paint method.
|
|
GNU Classpath Examples comes with a Demo, see examples/README.
|
|
* awt.datatransfer updated to 1.5 with supports for FlavorEvents.
|
|
The gtk+ awt peers now allow copy/paste of text, images, uris/files
|
|
and serialized objects with other applications and tracking
|
|
clipboard change events with gtk+ 2.6 (for gtk+ 2.4 only text and
|
|
serialized objects are supported). A GNU Classpath Examples
|
|
datatransfer Demo was added to show the new functionality.
|
|
* org.omg.PortableInterceptor and related functionality in other packages
|
|
is now implemented:
|
|
- The sever and client interceptors work as required since 1.4.
|
|
- The IOR interceptor works as needed for 1.5.
|
|
* The org.omg.DynamicAny package is completed and passes the prepared tests.
|
|
* The Portable Object Adapter should now support the output of the
|
|
recent IDL to java compilers. These compilers now generate servants and
|
|
not CORBA objects as before, making the output depended on the existing
|
|
POA implementation. Completing POA means that such code can already be
|
|
tried to run on Classpath. Our POA is tested for the following usager
|
|
scenarios:
|
|
- POA converts servant to the CORBA object.
|
|
- Servant provides to the CORBA object.
|
|
- POA activates new CORBA object with the given Object Id (byte array)
|
|
that is later accessible for the servant.
|
|
- During the first call, the ServantActivator provides servant for this
|
|
and all subsequent calls on the current object.
|
|
- During each call, the ServantLocator provides servant for this call
|
|
only.
|
|
- ServantLocator or ServantActivator forwards call to another server.
|
|
- POA has a single servant, responsible for all objects.
|
|
- POA has a default servant, but some objects are explicitly connected
|
|
to they specific servants.
|
|
The POA is verified using tests from the former cost.omg.org.
|
|
* The javax.swing.plaf.multi.* package is now implemented.
|
|
* Editing and several key actions for JTree and JTable were implemented.
|
|
* Lots of icons and look and feel improvements for Free Swing basic and
|
|
metal themes were added. Try running the GNU Classpath Swing Demo in
|
|
examples (gnu.classpath.examples.swing.Demo) with:
|
|
-Dswing.defaultlaf=javax.swing.plaf.basic.BasicLookAndFeel
|
|
-Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel
|
|
* Start of styled text capabilites for java.swing.text.
|
|
* NIO FileChannel.map implementation, fast bulk put implementation for
|
|
DirectByteBuffer (speeds up this method 10x).
|
|
* Split gtk+ awt peers event handling in two threads and improve gdk lock
|
|
handling (solves several AWT lock ups).
|
|
* Speed up awt Image loading.
|
|
* Updated TimeZone data against Olson tzdata2005l.
|
|
* Make zip and jar UTF-8 "clean".
|
|
* "native" code builds and compiles (warning free) on Darwin and Solaris.
|
|
|
|
Runtime interface changes:
|
|
|
|
* All native resource "pointers" in the VM interface classes are now exposed
|
|
as gnu.classpath.Pointer objects. This might impact runtimes that
|
|
optimize and support java.nio.DirectByteBuffers. Creating these classes
|
|
and accessing the contents as void * pointers for the native reference JNI
|
|
implementation is done through the JCL_NewRawDataObject and JCL_GetRawData
|
|
functions.
|
|
* Simplified the Class/VMClass interface.
|
|
* Removed loadedClasses map from ClassLoader. It's now the VMs responsibility
|
|
to manage the list of defined and loaded classes for each class loader.
|
|
* Moved native methods from java.lang.reflect.Proxy to VMProxy.
|
|
* Added hook to VMClassLoader to allow VM to do class caching.
|
|
|
|
New Untested/Disabled Features:
|
|
|
|
The following new features are included, but not ready for production
|
|
yet. They are explicitly disabled and not supported. But if you want
|
|
to help with the development of these new features we are interested
|
|
in feedback. You will have to explicitly enable them to try them out
|
|
(and they will most likely contain bugs). If you are interested in any
|
|
of these then please join the mailing-list and follow development in
|
|
CVS.
|
|
|
|
* QT4 AWT peers, enable by giving configure --enable-qt-peer.
|
|
* JDWP framework, enable by deleting the jdwp references from
|
|
lib/standard.omit and vm/reference/standard.omit. No default
|
|
implementation is provided. Work is being done on gcj/gij integration.
|
|
* StAX java.xml.stream, enable by deleting the gnu.xml.stream and
|
|
java.xml.stream references in lib/standard.omit.
|
|
|
|
New in release 0.17 (Jul 15, 2005)
|
|
|
|
* gnu.xml fix for nodes created outside a namespace context.
|
|
* Add support for output indenting and cdata-section-elements output
|
|
instruction in xml.transform.
|
|
* xml.xpath corrections for cases where elements/attributes might have
|
|
been created in non-namespace-aware mode. Corrections to handling of
|
|
XSL variables and minor conformance updates.
|
|
* DefaultMutableTreeNode preorder, postorder, depthFirst and breadthFirst
|
|
traversal enumerations implemented.
|
|
* JInternalFrame colors and titlebar draw properly.
|
|
* JTree is working up to par (icons, selection and keyboard traversal).
|
|
* JMenus were made more compatible in visual and programmatic behavior.
|
|
* JTable changeSelection and multiple selections implemented.
|
|
* JButton and JToggleButton change states work properly now.
|
|
* JFileChooser fixes.
|
|
* revalidate and repaint fixes which make Free Swing much more responsive.
|
|
* Correctly handle system call interrupts and timeouts in native nio
|
|
and net functions.
|
|
* MetalIconFactory implemented.
|
|
* Handle image loading errors correctly for gdkpixbuf and MediaTracker.
|
|
* Added Tree World to GNU Classpath examples Free Swing demo.
|
|
* FileChannel.lock() and FileChannel.force() implemented.
|
|
* java.util.logging.FileHandler now rotates files.
|
|
* Better handle GDK lock. Properly prefix gtkpeer native functions (cp_gtk).
|
|
* Corba bug fixes and documentation updates.
|
|
* Updated gcj build infrastructure.
|
|
* Documentation fixes all over the place.
|
|
See http://developer.classpath.org/doc/
|
|
* VM Integration Guide updates with a full section on VM/Classpath hooks.
|
|
|
|
New in release 0.16 (Jun 30, 2005)
|
|
|
|
* Better GTK scrollbar peer implementation when using GTK >= 2.6.
|
|
* GdkGraphics2D has been updated to use Cairo 0.5.x APIs.
|
|
* BufferedImage and GtkImage rewrites. All image drawing operations
|
|
should now work correctly (flipping requires gtk+ >= 2.6)
|
|
* Future Graphics2D, Image and Text work is documented at:
|
|
http://developer.classpath.org/mediation/ClasspathGraphicsImagesText
|
|
* Free Swing Top-Level Compatibility. JFrame, JDialog, JApplet,
|
|
JInternalFrame, and JWindow are now 1.5 compatible in the sense that you
|
|
can call add() and setLayout() directly on them, which will have the same
|
|
effect as calling getContentPane().add() and getContentPane().setLayout().
|
|
* The JTree interface has been completed. JTrees now recognizes mouse clicks
|
|
and selections work, but the visual implementation is not yet complete.
|
|
Work on expansion and collapsing of the tree nodes is being implemented.
|
|
* BoxLayout works properly now.
|
|
* Fixed GrayFilter to actually work.
|
|
* Metal SplitPane implemented.
|
|
* Lots of free swing text and editor stuff work now.
|
|
|
|
* When gtk+ 2.6 or higher is installed the default log handler will produce
|
|
stack traces whenever a WARNING, CRITICAL or ERROR message is produced.
|
|
|
|
* The CORBA implementation is now a working prototype that should support
|
|
features up till 1.3 inclusive.
|
|
We would invite groups writing CORBA dependent applications to
|
|
try Classpath implementation, reporting any possible bugs.
|
|
|
|
The CORBA prototype is interoperable with Sun's implementation v 1.4,
|
|
transferring object references, primitive types, narrow and wide
|
|
strings, arrays, structures, trees, abstract interfaces and
|
|
value types (feature of CORBA 2.3) between these two platforms.
|
|
The remote exceptions are transferred and handled correctly.
|
|
The stringified object references (IORs) from various sources are
|
|
parsed as required.
|
|
The transient (for current session) and permanent (till jre restart)
|
|
redirections work.
|
|
Both Little and Big Endian encoded messages are accepted.
|
|
The implementation is verified using tests from the former cost.omg.org.
|
|
The current release includes working examples (see the examples directory),
|
|
demonstrating the client-server communication, using either CORBA Request
|
|
or IDL-based stub (usually generated by a IDL to java compiler).
|
|
These examples also show how to use the Classpath CORBA naming service.
|
|
The IDL to java compiler is not yet written, but as our library must be
|
|
compatible, it naturally accepts the output of other idlj implementations.
|
|
|
|
* New --with-vm-classes configure option, and new 'build' setting
|
|
for --with-glibj. (Only for integrators.)
|
|
|
|
Runtime interface changes:
|
|
|
|
* Start of a generic JDWP framework in gnu/classpath/jdwp.
|
|
This is unfinished, but feedback (at classpath@gnu.org) from runtime
|
|
hackers is greatly appreciated. Although most of the work is currently
|
|
being done around gcj/gij we want this framework to be as VM neutral as
|
|
possible. Early design is described in:
|
|
http://gcc.gnu.org/ml/java/2005-05/msg00260.html
|
|
* Native method VMClass.getModifiers() now takes an additional
|
|
boolean parameter.
|
|
* Deprecated native method VMClassLoader.defineClass(ClassLoader,
|
|
String, byte[], int, int) has been replaced by
|
|
VMClassLoader.defineClass(ClassLoader, String, byte[], int, int,
|
|
ProtectionDomain)
|
|
* VMClassLoader.loadClass(String name, boolean resolve) is now native,
|
|
replacing the former version which just returned null.
|
|
* Deprecated native method VMClassLoader.getPrimitiveClass(String) has
|
|
been replaced by new native method VMClassLoader.getPrimitiveClass(char).
|
|
* Previously empty implementations of methods VMThread.countStackFrames(),
|
|
VMThrowable.fillInStackTrace(), and VMThrowable.getStackTrace() have
|
|
been removed; these methods are now native methods.
|
|
* Fields "exceptionTypes" and "parameterTypes" have been removed from
|
|
Contructor.java and getExceptionTypes() and getParameterTypes() are
|
|
now native methods.
|
|
|
|
New in release 0.15 (Apr 29, 2005)
|
|
|
|
* The old character encoding framework (gnu.java.io.EncodingManager)
|
|
has been replaced by a system based completely on nio.charset
|
|
providers. Many converters have been added, both the io, lang and nio
|
|
frameworks now use the same set of converters and the whole character
|
|
stream framework (Readers and Writers) have been optimized. For some
|
|
workloads this leads to 2x till 20x speedups.
|
|
|
|
The default charsets supported are:
|
|
|
|
Cp424, Cp437, Cp737, Cp775, Cp850, Cp852, Cp855, Cp857, Cp860, Cp861,
|
|
Cp862, Cp863, Cp864, Cp865, Cp866, Cp869, Cp874, ISO_8859_1, ISO_8859_13,
|
|
ISO_8859_15, ISO_8859_2, ISO_8859_3, ISO_8859_4, ISO_8859_5, ISO_8859_6,
|
|
ISO_8859_7, ISO_8859_8, ISO_8859_9, KOI_8, MS874, MacCentralEurope,
|
|
MacCroatian, MacCyrillic, MacDingbat, MacGreek, MacIceland, MacRoman,
|
|
MacRomania, MacSymbol, MacThai, MacTurkish, US_ASCII, UTF_16, UTF_16BE,
|
|
UTF_16Decoder, UTF_16Encoder, UTF_16LE, UTF_8, UnicodeLittle, Windows1250,
|
|
Windows1251, Windows1252, Windows1253, Windows1254, Windows1255,
|
|
Windows1256, Windows1257, Windows1258.
|
|
|
|
Many more encoding are supported through the new IconvProvider
|
|
depending on the platform iconv support. GNU libiconv is recommended.
|
|
The IconvProvider is currently not enabled by default. To enable it
|
|
define the system property gnu.classpath.nio.charset.provider.iconv=true.
|
|
Some runtimes might choose to enable this by default by setting it
|
|
through VMSystemProperties. We would like to get feedback on whether
|
|
enabling or disabling the IconvProvider by default results in the
|
|
highest speedups.
|
|
|
|
* Free swing metal and pluggable look and feels have been improved.
|
|
The GNU Classpath free swing example can now be run with different
|
|
"skins" by setting the system property swing.defaultlaf to the GNU,
|
|
Basic or Metal look and feel.
|
|
|
|
* Some of the org.omg.CORBA classes and packages have now been
|
|
implemented. The Savannah bug tracker contains additional tasks for
|
|
which we are seeking help.
|
|
|
|
* Fixed compatibility problems in the java.beans which affected
|
|
Eclipse's Visual Editor Project.
|
|
|
|
* New completely lock free (Inheritable)ThreadLocal implementation.
|
|
|
|
* javax.swing.text.rtf framework added which can handle simple (plain)
|
|
text tokens.
|
|
|
|
* Support for parsing html files into Level 2 Document Object Model
|
|
(org.w3c.dom.html2 and javax.swing.text.html.parser). And a start of
|
|
javax.swing.text.html framework added.
|
|
|
|
Runtime interface changes:
|
|
|
|
* jni.h changed to better support compiling runtimes implementing jni;
|
|
see VM integration guide for details.
|
|
* New --enable-default-toolkit option to configure can be used to set
|
|
the fully qualified class name of the default AWT toolkit to use.
|
|
If not given, the old default of gnu.java.awt.peerk.gtk.GtkToolkit
|
|
is used.
|
|
* New --disable-core-jni option can be used to disable building the
|
|
"core" JNI libraries. This is primarily useful if your VM can use the
|
|
Gtk peers but not the core JNI libraries.
|
|
* New system property "gnu.classpath.boot.library.path" can be specified
|
|
to define the location of the JNI libraries. It is by all means meant
|
|
ONLY for VM implementors and GNU Classpath hackers. See the hacking
|
|
guide for more information.
|
|
* The helper methods currentLoader() and allocateObject() for
|
|
java.io.ObjectInputStream have been moved to a VMObjectInputStream class.
|
|
Reference implementations are provided.
|
|
* java.net.InetAddress now uses VMInetAddress for runtime/platform
|
|
specific methods getLocalHostname(), getHostByAddr() and
|
|
getHostByName(). java.net.NetworkInterface now uses VMNetworkInterface
|
|
for runtime/platform specific getInterfaces() support. Default
|
|
(Posix/GNU JNI) implementations are provided.
|
|
* VMClass has a new method getModifiers(Class, boolean) which can be
|
|
used to get the real modifiers for an inner class or the ones
|
|
specified by the InnerClasses attribute.
|
|
* All (possible) runtime specific methods of Object and Double are now
|
|
in VMObject and VMDouble. Where possible generic reference
|
|
implementations are provided.
|
|
* The reference implementation of VMClassLoader now handles zip files
|
|
on the boot loader class path in getResources().
|
|
|
|
Other changes:
|
|
|
|
New in release 0.14 (Feb 25, 2005)
|
|
|
|
* Character encoders and decoders have been added for:
|
|
iso-8859-6 (arabic), iso-8859-7 (greek), iso-8859-8 (hebrew),
|
|
iso-8859-9 (latin-5), iso-8859-13, iso-8859-15 (latin-9), cp1047 (ebcdic),
|
|
ebcdic-xml-us,ascii, windows-1250, windows-1252, UTF-16BE (Big Endian),
|
|
UTF-16LE (Little Endian), UTF-32BE (Big Endian), UTF-32LE (Little Endian).
|
|
* Full documentation for all classes can be generated (again) by using
|
|
the --with-gjdoc configure option.
|
|
* javax.awt.imageio support through gdkpixbuf.
|
|
|
|
Runtime interface changes:
|
|
|
|
* VMSecurityManager has been replaced by gnu.classpath.VMStackWalker.
|
|
currentClassLoader() is no longer needed, and there are also two new
|
|
methods with non-native implementations. VM implementors are encouraged
|
|
to provide more efficient versions.
|
|
* VMRuntime.nativeLoad() now takes an additional ClassLoader parameter.
|
|
|
|
New in release 0.13 (Jan 6, 2005)
|
|
|
|
* The http url protocol handler has been replaced with a full HTTP/1.1
|
|
version from GNU inetlib.
|
|
* A new ftp url protocol handler has been added also from GNU inetlib.
|
|
* java.beans has been updated to 1.4 including support for XMLEncoder
|
|
and XMLDecoder.
|
|
* The java.util.Locale support is now based on the Common Locale Data
|
|
Repository (CLDR) Project (see http://www.unicode.org/cldr/).
|
|
GNU Classpath provides support for more than 250 locales now.
|
|
This new support is experimental and the GNU Classpath hackers are
|
|
working together with runtime developers and the unicode consortium
|
|
to improve them in the future.
|
|
If your runtime misdetects your locale or if the default locale gives
|
|
problems please try running with -Duser.language=en and -Duser.region=US
|
|
to fall back on a known good locale.
|
|
* Added implementations of javax.xml (JAXP 1.3), org.xml.sax (SAX2) and
|
|
org.w3c.dom (DOM Level 3) interfaces. It is possible to switch between
|
|
different implementations AElfred2, GNU DOM, GNU XSL, libxmlj SAX,
|
|
libxmlj DOM and libxmlj XSL by setting different system properties.
|
|
Also provided is a preliminary XPath 1.0 implementation.
|
|
The libxmlj versions are build around libxml2 and libxslt and have to
|
|
be enabled during build time by the --enable-xmlj configure flag.
|
|
The current support is equal to the last released GNU JAXP 1.3 release.
|
|
These packages will be maintained as part of the GNU Classpath core classes
|
|
in the future. For more information, conformance results and documentation
|
|
on selecting different implementations see doc/README.jaxp.
|
|
* More AWT accessible support.
|
|
* AWT gtk+ peers component layout, dialog placement, keyboard focus
|
|
handling and text positioning have been improved.
|
|
* ImageIO interfaces are more complete.
|
|
* JList, JTable and JTree have been hugely improved.
|
|
* java.awt.Robot support with GdkRobot in the gtk+ awt peers.
|
|
Needs XTest Extension (libXtst) XServer support.
|
|
* New --disable-examples configure argument.
|
|
|
|
Runtime interface changes:
|
|
|
|
* Added a new method (VMRuntime.enableShutdownHooks) that enables the VM
|
|
to lazily register an exit handler.
|
|
* The java.lang.Class constructor now automatically sets the protection
|
|
domain for array classes, based on the protection domain of the component
|
|
type class.
|
|
* New gnu.classpath.VMSystemProperties class. This replaces the
|
|
system properties initialization in VMRuntime. Note that it is
|
|
now the VMs responsibility to set one additional property:
|
|
gnu.cpu.endian should be set to "big" or "little".
|
|
* VMRuntime.nativeGetLibname() has been renamed to VMRuntime.mapLibraryName()
|
|
and has only one argument, the name of the library.
|
|
* String and StringBuffer now call VMSystem.arraycopy() directly and don't
|
|
go through java.lang.System. Be careful to not initialize java.lang.System
|
|
early in the bootstrap sequence in your VM runtime interface classes.
|
|
* Some (wrong) documentation about the behavior of VMThread.sleep(0, 0)
|
|
has been updated. Also, VMThread.sleep() now has a default non-native
|
|
implementation, but it is a generic implementation that ignores the
|
|
nano-seconds argument. Runtime hackers are encouraged to provide a more
|
|
efficient version.
|
|
* There is prelimenary support for nio direct byte buffers.
|
|
See VMDirectByteBuffer. Please contact the GNU Classpath mailinglist when
|
|
you add support for this to your runtime.
|
|
|
|
New in release 0.12 (Nov 14, 2004)
|
|
|
|
* GNU Classpath's JAR implementation now has preliminary support for
|
|
signed entries, for so called "signed JAR" file support. Signed JAR
|
|
files are one of the key security features of managed runtimes, and
|
|
allows code to run privileged given unforgeable proofs of identity.
|
|
* A much improved version of X.509 certificates has been added,
|
|
including a robust certificate path checking algorithm. Also
|

|
|
option. (Warning, will be replaced in next release, please consult
|
|
the mailinglist.)
|
|
* The reference implementation of VMClassLoader has default
|
|
implementations for getResource(s) and provides support for a new
|
|
default getSystemClassLoader implementation.
|
|
|
|
New in release 0.11 (Sep 13, 2004)
|
|
|
|
* javax.swing.Spring and SpringLayout support.
|
|
* Added pluggable look and feel support for BasicTextFieldUI and
|
|

|
|
javax.net.ssl, javax.security.auth, javax.security.auth.callback,
|
|
javax.security.auth.login, javax.security.auth.x500, javax.security.sasl
|
|
and org.ietf.jgss packages are now officially part of GNU Classpath.
|
|
Extra crypto algorithms can be obtained from the GNU Crypto project,
|
|
a full TLS implementation is provided by the Jessie project.
|
|
http://www.gnu.org/software/gnu-crypto/
|
|
http://www.nongnu.org/jessie/
|
|
* Frame.setIconImage() support.
|
|
* AWT GDKGraphics scaling.
|
|
* New configure flag --enable-gtk-cairo to build Graphics2D implementation
|
|
build on cairo and pangoft2. Enabled at runtime by defining the system
|
|
property gnu.java.awt.peer.gtk.Graphics=Graphics2D.
|
|
* javax.swing.JSpinner implemented.
|
|
* Extensive documentation update for java.util collection classes.
|
|
* java.awt.geom completed. Area, Arc2D, Ellipse2D and Line2D implemented.
|
|
* GNU JAXP is no longer included with GNU Classpath. Runtime, compiler and
|
|
tool integrators are encouraged to directly integrate GNU JAXP.
|
|
This release has been tested against GNU JAXP 1.1.
|
|
http://www.gnu.org/software/classpathx/jaxp/jaxp.html
|
|
* JColorChooser, JComboBox and JTextField implemented, including example
|
|
uses in GNU Classpath Examples swing Demo.
|
|
|
|
Runtime interface Changes:
|
|
|
|
* java.lang.Compiler now uses the new java.lang.VMCompiler; there is
|
|
a reference implementation that most VMs can use.
|
|
* java.lang.VMSystem has a new getenv(String) method and a reference C/JNI
|
|
implementation that should work on most Posix like systems.
|
|
* java.util.TimeZone has been split into a platform independent class and
|
|
a platform dependent class VMTimeZone. GNU Classpath comes with a generic
|
|
way to get at the default time zone for Posix/GNU-like platforms.
|
|
* [VM]AccessController improvements. In particular it handles
|
|
`doPrivileged' calls better, and allows for recursive `doPrivileged'
|
|
calls in the same Thread. (see vm/reference/java/security/)
|
|
|
|
New in release 0.10 (Jul 9, 2004)
|
|
|
|
* java.net.URL now uses application classloader to load URLStreamHandlers
|
|
and reuses URLStreamHandlers when URL is reset (but protocol isn't changed).
|
|
* java.io.File.deleteOnExit() implementation.
|
|
* java.text multiple new features and bug fixes
|
|
(only 2 out of the 1000+ java.text Mauve tests now fail).
|
|
* Better (non-black) default AWT System colors.
|
|
* AWT lists use GTK treeviews.
|
|
* Proper AWT focus management has been implemented.
|
|
* Swing menus and scrollpanes are beginning to work.
|
|
* Swing splitpanes, dialogs and internal frames were added.
|
|
* Swing repainting / double buffering was redone.
|
|
* Font management and Pango DPI conversion fixes.
|
|
* A lot of AWT imaging and event bugs have been picked out.
|
|
* More of javax.swing.text has been implemented.
|
|
* javax.swing.Timer has been reimplemented.
|
|
* java.security.AccessController has been implemented
|
|
(see runtime section).
|
|
* The default java.lang.SecurityManager now uses AccessController.
|
|
* New java.beans.Statement and Expression implementations.
|
|
* Small FileChannel implementation speed improvement for traditional
|
|
JNI based systems.
|
|
* Regenerated all included JNI header files with gcjh (3.5 CVS),
|
|
removes extra extern modifier and allows stricter compiler warning.
|
|
* More C code cleanups (-Wmissing-declarations, -Wmissing-prototypes and
|
|
-Wstring-prototypes) and jni.h fixes (a few funtion prototype fixes,
|
|
made it compilable with C++ compilers and jni.h got renamed from jni.h.in).
|
|
* Double.toString() and Float.toString() now work properly on 64-bit
|
|
PowerPC systems.
|
|
* PPC Darwin, arm, x86-64 and s/390 JNI C code compilation fixes.
|
|
* Build system refactored and removed old Japhar specific support.
|
|
* The gnu.java.awt.EmbeddedWindow class has been improved, and now
|
|
supports embedding AWT windows in other top-level X windows.
|
|
This functionality is required by gcjwebplugin.
|
|
* gcjwebplugin, an applet viewer that can be embedded into several web
|
|
browsers, has been extensively tested with this release of classpath.
|
|
(See http://www.nongnu.org/gcjwebplugin/)
|
|
* Runtime environments based on GNU Classpath 0.10 should be able to
|
|
start up Eclipse 3.0 out of the box now.
|
|
|
|
Runtime interface Changes:
|
|
|
|
* VMProcess.destroy() default implementation fixes.
|
|
* Fixed the "portable native sync" code; it had been broken since
|
|
Classpath release 0.06, when we upgraded to GTK+2.
|
|
Classpath's AWT peers use GTK+. GTK+ uses GLIB. GLIB by default uses
|
|
the platform's native threading model -- pthreads in most cases.
|
|
If the Java runtime doesn't use the native threading model, then you should
|
|
specify --portable-native-sync when configuring Classpath, so that GLIB will
|
|
use the Java threading primitives instead. (For a superior alternative,
|
|
see below.)
|
|
* The VM can set the system property
|
|
gnu.classpath.awt.gtk.portable.native.sync instead of using the
|
|
--portable-native-sync configure-type option.
|
|
See doc/vmintegration.texinfo for details.
|
|
* We intend that the next release of GNU Classpath will require the VM
|
|
to provide JNI 1.2. Classpath currently uses only JNI 1.1, except for
|
|
one JNI 1.2 function: GetEnv(), in the JNI Invocation API.
|
|
If this poses problems, please raise them on the classpath mailing list.
|
|
* The reference implementation of VMThread.holdsLock(Object) now has
|
|
a default implementation written in java. For efficiency and to
|
|
prevent spurious wakeups a real 'native' runtime version can be supplied.
|
|
* There is a new java.security.VMAccessController class that runtimes need
|
|
to implement to properly support SecurityManagers. The default
|
|
implementation that comes with GNU Classpath makes sure that ANY attempt
|
|
to access a protected resource is denied when a SecurityManager is
|
|
installed. Which is pretty secure, but also no very useful.
|
|
Please see the documentation in
|
|
vm/reference/java/security/VMAccessController.java,
|
|
and please give feedback on the GNU Classpath mailinglist whether or not
|
|
the current AccessController framework is flexible enough.
|
|
|
|
New in release 0.09 (May 2, 2004)
|
|
|
|
* Includes updated GNU JAXP version from 2004-02-01.
|
|
* Native C code is now -ansi -pedantic (C89) clean and (almost) -Wall clean.
|
|
* java.io is now implemented by delegating most tasks directly to java.nio.
|
|
* Reworked/Optimized implementations of java.nio.Buffer and subclasses.
|
|
* New javax.print, javax.print.attribute[.standard] and javax.print.event
|
|
packages and classes.
|
|
* java.text attributed iterators support.
|
|
* New javax.imageio, javax.imageio.event and javax.imageio.spi packages and
|
|
classes.
|
|
* GNU Classpath can now load service providers that are described via
|
|
META-INF/services/* resources in extension JARs. This is useful for
|
|
implementing the various APIs that are supposed to be extensible via
|
|
custom plugins. For details, please see the documentation of
|
|
gnu.classpath.ServiceFactory.
|
|
Application developers are strongly discouraged from calling glibj
|
|
internal packages. Instead, they might want invoke the newly implemented
|
|
javax.imageio.spi.ServiceRegistry.lookupProviders, which is a standard
|
|
method for loading plug-ins.
|
|
* New developers wanting to help the GNU Classpath project might want to
|
|
review the greatly expanded Hacker Guide included in the doc directory
|
|
or online at http://www.gnu.org/software/classpath/docs/hacking.html
|
|
Also the FAQ has been expanded. And when working from CVS you can now use
|
|
a simple autogen.sh script to get all autotools magic done automagically.
|
|
* New configure option --with-glibj which defines how to install the glibj
|
|
class files as zip, as flat directory files or both (zip|flat|both)
|
|
[default=zip]. When working with multiple runtimes some of which might
|
|
not support bootstrap classes in zip files the --with-glibj=both option
|
|
is recommended (this does take extra disc space).
|
|
* Two big code drops from the libgcj gui branch updating various java.awt
|
|
and javax.swing classes.
|
|
* Multiple java.net.InetAdress fixes and java.rmi fixes.
|
|
* ServerSocket.accept() now restarts listening when system call interrupted.
|
|
* Much cleanups to make standard API doc valid XHTML (not completed yet).
|
|
* A scan for unused variables and non-static invocation of static methods
|
|
turned up a couple of subtle bugs which have now all been fixed.
|
|
* The Mauve testsuite has been cleaned up considerable and lots of issues
|
|
in the GNU Classpath core class implementation have been fixed.
|
|
|
|
VM Interface changes:
|
|
|
|
* java.lang.Class/VMClass interface was changed. The interface now no
|
|
longer requires an instance of VMClass for each Class instance. Instead
|
|
the field vmdata in Class is now of type Object.
|
|
* GNU Classpath now assumes that JNI calls SetXField can modify final
|
|
fields. This was previously used silently for System.in/out/err and should
|
|
be considered as a feature now.
|
|
* A new VMProcess and a sample JNI C implementation are now provided to
|
|
make Runtime.exec() work out of the box on some systems. This requires
|
|
a small change to VMRuntime.exec() when a runtime wants to use it as the
|
|
default java.lang.Process implementation.
|
|
* The implementation of most of java.io through java.nio moved serveral
|
|
runtime specific I/O methods. Most methods do have a generic default native
|
|
C JNI implementation in native/jni/java-nio.
|
|
* Runtime support methods for java.io.File have been moved to VMFile which
|
|
also comes with a default JNI C implementation.
|
|
* To support the new service provider mechanism runtimes must make sure that
|
|
extension JARs are made accessible via the default context class loader.
|
|
|
|
New in release 0.08 (2004/12/03)
|
|
|
|
* java.util.regexp implementation through gnu.regexp wrappers.
|
|
* java.net.URI implementation.
|
|
* Working implementation of javax.swing.undo.
|
|
* java.awt.geom.CubicCurve2D/QuadCurve2D: Can now solve cubic and quadratic
|
|
equations; implementation adapted from the GNU Scientific Library.
|
|
* Lots of java.awt and gtk+ peer improvements. Also more Swing work. Start
|
|
of EmbeddedWindow support.
|
|
* BufferedReader speed improvements.
|
|
* Improved useabilty of java.text implementation for several applications.
|
|
* ObjectInputStream is much faster and more compatible with other
|
|
implementations.
|
|
* Fix handling of alias methods, where a method has been deprecated in
|
|
favour of a new one with the same funtion but a different name.
|
|
(See Deprecated Methods section in the GNU Classpath Hacking Guide.)
|
|
* javax.print.attribute.standard added.
|
|
* Lots of java.nio, java.net, java.io
|
|
* Depend on autoconf 2.59+ and automake 1.7+, GCJ 3.3+, jikes 1.18+.
|
|
|
|
VM Interface changes:
|
|
* Split native methods in java.lang.Runtime into java.lang.VMRuntime.
|
|
* Resources are now also loaded/needed through the bootstrap classloader
|
|
(gnu.regexp needs MessageBundle included in glibj.zip
|
|
|
|
Fixed Classpath bugs:
|
|
#6095 java.awt.geom.QuadCurve2D.solveQuadratic sometimes gives
|
|
wrong results
|
|
#7099 EventListenerList.getListenerCount should accept null argument
|
|
#7104 EventListenerList.add does not work
|
|
#7105 EventListenerList.remove does not work
|
|
#7107 DefaultBoundedRangeModel.setValue and friends should not throw
|
|
And lots more.
|
|
|
|
New in release 0.07 (2003/30/11)
|
|
|
|
* Works with libtool 1.5 (and 1.4.3).
|
|
* java.awt gtk+ peers now depend on gtk+ 2.2.x and uses pango.
|
|
Lots and lots improvements on the peers.
|
|
* java.awt.geom.CubicCurve2D, java.awt.geom.QuadCurve2D:
|
|
Subdivision and flatness calculation implemented.
|
|
* java.awt.geom.FlatteningPathIterator: Working implementation.
|
|
* gnu.java.awt.BitwiseXORComposite helper class.
|
|
* New rmic compilers (jikes, kjc) support.
|
|
* java.text bug fixing and 1.4 updates (Currency).
|
|
* Hashtable and HashMap function more similar to other implementations.
|
|
* javax.naming and java.beans classloader fixes.
|
|
* URL parsing, URLConnection, protocol and (needed) permission fixes.
|
|
* More java.nio implementation
|
|
(API complete, but implementation not finished yet).
|
|
* Lots of java.net code cleanup.
|
|
* Improved documentation.
|
|
* Numerous bug fixes in almost every package, and lots of updates for
|
|
1.4 functionality.
|
|
* Fixed Classpath bugs:
|
|
#2944 Incorrect synchronization in java.util.logging.ErrorManager
|
|
#6075 java.awt.geom.GeneralPath.getCurrentPoint returns wrong results
|
|
#6076 java.awt.geom.GeneralPath constructor sometimes hangs
|
|
#6089 java.awt.geom.GeneralPath.getPathIterator does not work
|
|

|
|
VM Interface changes:
|
|
|
|
* Thread has been split in a VM-independent Thread class and a VM-dependent
|
|
VMThread class.
|
|
|
|
New in release 0.06 (2003/22/08)
|
|
|
|
* Update java.awt peers to GTK+2.
|
|
* java.awt.GridBagLayout implementation.
|
|
* javax.swing.border implementation.
|
|
* java.security and java.security.cert updated to 1.4 spec.
|
|
* New JNI native target code layer. See native/target/readme.txt.
|
|
* --enable-regen-headers configure flag for automatic jni .h file generation.
|
|
* Removed workaround for gcj 3.2 and lower, gcj 3.3+ or jikes 1.18+ is now
|
|
needed for compiling.
|
|
* Lots of improvements and/or new classes for java.awt, java.awt.dnd,
|
|
java.awt.font, java.awt.geom, java.awt.image, java.io, java.math, java.net,
|
|
java.nio, java.rmi, java.text, java.util, javax.swing, javax.swing.plaf,
|
|
javax.swing.text.
|
|
|
|
VM Interface changes:
|
|
|
|
* VMClassLoader.loadClass(), the bootstrap classloader called by
|
|
Class.forName() and ClassLoader.loadClass(), may now return null when
|
|
a class is not found instead of throwing a new ClassNotFoundException.
|
|
This is a performance optimization in some cases. This also changes
|
|
the Class.forName() reference code.
|
|
* Native methods in Class have been moved to VMClass. A few additional
|
|
methods are also available in VMClass to provide optional performance
|
|
improvements.
|
|
* A VM can now supply its own String.intern() strategy through the
|
|
VMString class. The supplied VMString reference class implements the
|
|
original WeakHashMap strategy.
|
|
* Float and Double to/from bits conversion functions can now be supplied by
|
|
the VM through VMFloat and VMDouble. Default JNI conversion methods are
|
|
supplied.
|
|
|
|
New in release 0.05 (2003/02/15)
|
|
* Supports free Java VMs Jikes RVM and Kissme out of the box, perhaps others.
|
|
* Supports GNU Crypto 1.1 as the official provider of cryptographic primitives
|
|
and tools for GNU Classpath, available separately from
|
|
http://www.gnu.org/software/classpathx/crypto/crypto.html.
|
|
* Supports GNU Classpath Tools sub-project of GNU Classpath, official provider
|
|
of standard tools such as gjdoc, a javadoc replacement, and others. Future
|
|
releases of GNU Classpath will begin to include these tools, available
|
|
separately from http://www.gnu.org/software/cp-tools/.
|
|
* Java primitives can be used to support AWT native threading, see
|
|
the --enable-portable-native-sync configure option which may become the
|
|
default in a future release.
|
|
* Include file jni.h has been updated to the 1.4 specification.
|
|
* VM specific internal types for jobject, jfieldID, and jmethodID are
|
|
supported in jni.h. More details can be found by reading the comment
|
|
in include/jni.h.in. By default the old definitions are used instead.
|
|
* New VM helper class java.io.VMObjectStreamClass which should provide
|
|
the hasClassInitializer() method. Previously ObjectStreamClass used
|
|
Class.getDeclaredMethod("<clinit>") but according to the spec this
|
|
should always throw NoSuchMethodException for class initialization methods.
|
|
A JNI reference implementation is provided as
|
|
vm/reference/java-io/java_io_VMObjectStreamClass.c
|
|
* There have been numerous infrastructure improvements
|
|
* Configure option --enable-gjdoc to generate javadoc-like output
|
|
* Gjdoc output is included with distribution, see doc/api/html/
|
|
* DESTDIR fully supported for install and uninstall
|
|
* Runtime.execInternal contract changed to allow for null `env'
|
|
and to accept `dir' argument.
|
|
* VMObject.getClass() removed. It was never used.
|
|
* java.lang.Throwable is now a 'normal' GNU Classpath class that uses the
|
|
VM specific java.lang.VMThrowable to get at the VM state and (if needed)
|
|
the StackTraceElements for a particular exception. A default implementation
|
|
(that does nothing) is provided in vm/reference/java/lang/VMThrowable.java.
|
|
* The vm/reference classes from the gnu.vm.stack and their counterparts
|
|
ExecutionStack and StackFrame in gnu.java.lang have been removed since they
|
|
are not actually part of the VM interface anyway.
|
|
* The GPLed com.sun.javadoc classes have been moved to the gjdoc application
|
|
from the GNU Classpath Tools project. See for more information the homepage
|
|
at: <http://www.gnu.org/software/cp-tools/>.
|
|
|
|
New in release 0.04 (2002/05/05)
|
|
* Additional configure options to disable zip creation and installation as
|
|
well as disable gtk peer native compilation.
|
|
* Addition of java.nio, java.util.logging, and javax.swing.
|
|
* Integration of most or all of the ORP patches to date, the purpose of
|
|
which are to make it possible to use JBOSS with ORP and Classpath. This
|
|
is still in a testing phase however.
|
|
* Significant changes in the reference VM interface that may require
|
|
support from the JVMs.
|
|
* Lots of bugfixes.
|
|
|
|
New in release 0.03 (2002/02/08)
|
|
* More merges with libgcj have been performed including java.math which now
|
|
provides a pure Java implementation of that package.
|
|
Current status at <http://gcc.gnu.org/java/libgcj-classpath-compare.html>
|
|
* A pure Java implementation (Jazzlib) of java.util.zip is available.
|
|
* Added the java.rmi implementation that Transvirtual donated to the FSF.
|
|
* Includes jni.h now, eliminating the need to specify a particular VM
|
|
via configure.
|
|
* No proprietary classes or programs are required to compile.
|
|
Compiles out of the box with jikes or gcj.
|
|
* Separation of compiling Java source and native libraries through the
|
|
configure mechanism. If given no arguments, configure will setup the
|
|
subsequent build to only produce Java bytecode (.class files). More
|
|
information is available in INSTALLING.
|
|
* Support for compiling in a separate directory, as an example you may
|
|
cd classpath-0.03; mkdir build; cd build; ../configure; make
|
|
* Works with Orp 1.0.9 out of the box. Build instructions can be found at
|
|
<http://www.gnu.org/software/classpath/doc/orp.html>
|
|
* Lots of bugfixes that were found by using Classpath with the gcj, Orp,
|
|
SableVM, KissMe and Jaos VMs. Please use our bugdatabase at
|
|
<http://savannah.gnu.org/support/?group_id=85>
|
|
* Lots of updates to make Classpath more compliant with the 1.2, 1.3 and 1.4
|
|
API specification. The current status can be found at
|
|
<http://www.gnu.org/software/classpath/status.html>
|
|
* All files are now distributed under the same terms. Added clarification to
|
|
GPL exception.
|
|
|
|
New in release 0.02 (2001/01/06)
|
|
* Support for printing exceptions with Japhar 0.09 + patch included in
|
|
resource/japhar-0.09.patch.1.
|
|
* Typos, assorted bugfixes.
|
|
|
|
New in release 0.01 (2000/11/20)
