*** Changes in GCC 4.0:
|
|
|
|
* 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).
|
|
|
|
* Lots of Calendar bug fixes.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* Much fuller collection documentation.
|
|
|
|
* libgcj 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.
|
|
|
|
* 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 included
|
|
is an implementation of the RSA signature scheme.
|
|
|
|
* New javax.crypto, javax.crypto.interfaces, javax.crypto.spec,
|
|
javax.net, 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.

|
|
|
|

|
|
|
* The default java.lang.SecurityManager now uses AccessController.
|
|
|
|
* Lookahead support for regular expressions.
|
|
|
|
* java.util.regexp implementation through gnu.regexp wrappers.
|
|
|
|
* Serialization object stream fixes for multiple ClassLoader scenarios.
|
|
|
|
* 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.io is now implemented by delegating most tasks directly to
|
|
java.nio.
|
|
|
|
* Reworked/Optimized implementations of java.nio.Buffer and subclasses.
|
|
|
|
* BufferedReader speed improvements.

|
|
*** Changes in GCC 3.4:
|
|
|
|
* Compiling a .jar file will now cause non-.class entries to be automatically
|
|
compiled as resources.
|
|
|
|
* libgcj has been ported to Darwin.
|
|
|
|
* Jeff Sturm has adapted Jan Hubicka's call graph optimization code to gcj.
|
|
|
|
* libgcj has a new gcjlib URL type; this lets URLClassLoader load code from
|
|
shared libraries.
|
|
|
|
* libgcj has been much more completely merged with GNU Classpath.
|
|
|
|
* Class loading is now much more correct; in particular the caller's class
|
|
loader is now used when that is required.
|
|
|
|
* Eclipse 2.x will run out of the box using gij.
|
|
|
|
* Parts of java.nio have been implemented. Direct and indirect buffers work,
|
|
as do fundamental file and socket operations.
|
|
|
|
* java.awt has been improved, though it is still not ready for general use.
|
|
|
|
* The HTTP protocol handler now uses HTTP/1.1 and can handle the POST method.
|
|
|
|
* The MinGW port has matured. Enhancements include socket timeout support,
|
|
thread interruption, improved Runtime.exec() handling and support for
|
|
accented characters in filenames.
|
|
|
|
*** Changes in GCC 3.3:
|
|
|
|
* The java.sql and javax.sql packages now implement the JDBC 3.0 (JDK 1.4)
|
|
API.
|
|
|
|
* The JDK 1.4 assert facility has been implemented.
|
|
|
|
* The bytecode interpreter is now direct threaded and thus faster.
|
|
|
|
|
|
*** Changes in GCC 3.1:
|
|
|
|
* libgcj now includes RMI, java.lang.ref.*, javax.naming, and
|
|
javax.transaction.
|
|
|
|
* Property files and other system resources can be compiled into executables
|
|
which use libgcj using the new gcj --resource feature.
|
|
|
|
* libgcj has been ported to more platforms. In particular there is now a
|
|
mostly-functional mingw32 (Windows) target port.
|
|
|
|
* JNI and CNI invocation interfaces were implemented, so gcj-compiled Java
|
|
code can now be called from a C/C++ application.
|
|
|
|
* gcj can now use builtin functions for certain known methods, for instance
|
|
Math.cos.
|
|
|
|
* gcj can now automatically remove redundant array-store checks in some common
|
|
cases.
|
|
|
|
* The --no-store-checks optimization option was added. This can be used to
|
|
omit runtime store checks for code which is known not to throw
|
|
ArrayStoreException
|
|
|
|
* The following third party interface standards were added to libgcj:
|
|
org.w3c.dom and org.xml.sax.
|
|
|
|
* java.security has been merged with GNU Classpath. The new package is now
|
|
JDK 1.2 compliant, and much more complete.
|
|
|
|
* A bytecode verifier was added to the libgcj interpreter.
|
|
|
|
* java.lang.Character was rewritten to comply with the Unicode 3.0 standard,
|
|
and improve performance.
|
|
|
|
* Partial support for many more locales was added to libgcj.
|
|
|
|
* Socket timeouts have been implemented.
|
|
|
|
* libgcj has been merged into a single shared library. There are no longer
|
|
separate shared libraries for the garbage collector and zlib.
|
|
|
|
* Several performance improvements were made to gcj and libgcj:
|
|
o Hash synchronization (thin locks)
|
|
o A special allocation path for finalizer-free objects
|
|
o Thread-local allocation
|
|
o Parallel GC, and other GC tweaks
|
|
|
|
*** Changes in GCC 3.0:
|
|
|
|
* libgcj now includes a bytecode interpreter. If a compiled version of a class
|
|
is not found in the application binary or linked shared libraries, the
|
|
class loader will search for a bytecode version in the CLASSPATH and execute
|
|
it using the interpreter. A new front end that behaves like the traditional
|
|
`java' command is also provided: `gij'.
|
|
|
|
* Support for specifying java system properties. Properties can either be set
|
|
at runtime via the GCJ_PROPERTIES environment variable in the format
|
|
"<name>=<value> ..."'; or can be compiled into an application binary using
|
|
-D<name>=<value>.
|
|
|
|
* Support for setjmp/longjmp (sjlj) exception handling has been added, as an
|
|
alternative to the existing range-table based mechanism. sjlj is the default
|
|
on non-sparc, non-x86 targets, or can be specified with the
|
|
`--enable-sjlj-exceptions' configure parameter.
|
|
|
|
* Complete JDK 1.1 reflection support, including invocation.
|
|
|
|
* Throwable.printStackTrace() has been implemented.
|
|
|
|
* Runtime.loadLibrary() has been implemented.
|
|
|
|
* Class.forName() will now try to load a series of shared objects in order
|
|
to find the requested class. If a class `gnu.quux.whatever' is requested,
|
|
libgcj will search the system shared library path (eg LD_LIBRARY_PATH) for
|
|
`gnu-quux-whatever.so', then `gnu-quux.so', and finally `gnu.so'.
|
|
|
|
* A pure-java implementation of java.math.BigInteger.
|
|
|
|
New in libgcj 2.95:
|
|
|
|
* First public release
