* java/lang/natClassLoader.cc: Include VirtualMachineError.h
(_Jv_RegisterClassHookDefault): Throw error if a class is
registered twice.
Co-Authored-By: Tom Tromey <tromey@redhat.com>
From-SVN: r45418
* java/lang/ClassLoader.java (system): Remove static field.
(getSystemClassLoader): Get gnu.gcj.runtime.VMClassLoader.instance
directly instead of using it to set the system field.
(loadClass): Use VMClassLoader.instance instead of system field.
(findSystemClass): Similar.
* prims.cc (_Jv_RunMain): Clear VMClassLoader::instance rather
than ClassLoader::system which no longer exists.

From-SVN: r45343
* Makefile.am: New friends for java/lang/Thread.h.
* prims.cc (runFirst): Removed.
(JvRunMain): Merged into _Jv_RunMain. Now just calls that.
(_Jv_RunMain): Now takes either a klass or class name parameter.
Create a gnu.gcj.runtime.FirstThread and attach the native thread
to that, then run it using _Jv_ThreadRun. Remove special handling of
jar files, instead pass is_jar parameter through to FirstThread.
* gcj/javaprims.h: Add prototypes for _Jv_ThreadRun and new variant
of _Jv_AttachCurrentThread.
* gnu/gcj/runtime/FirstThread.java (FirstThread): Now extends Thread.
(run): New method. Take care of looking up main class manifest
attribute and calling forName if neccessary. Then call call_main.
(call_main): New native method.
* gnu/gcj/runtime/natFirstThread.cc (call_main): New function, code
relocated from prims.cc. Look up and call main method.
* java/lang/Thread.java (run_): Removed.

(_Jv_ThreadRun): this. JVMPI notification code moved to ...
(_Jv_NotifyThreadStart): here. New function.
(countStackFrames, destroy, resume, suspend, stop): Throw
UnsupportedOperationExceptions rather than JvFail'ing.
(_Jv_AttachCurrentThread): New variant takes a Thread argument.
Existing version wraps new variant.
From-SVN: r45182
* java/lang/natRuntime.cc (_Jv_FindSymbolInExecutable): Return
NULL if no library on the list has the symbol.
(init): Call add_library on the program itself.

Bryce McKinlay <bryce@waitaki.otago.ac.nz>
* java/lang/natClass.cc (_Jv_IsAssignableFrom): Ensure that ancestors
table index is within allowed bounds. Ensure that we dont try to access
class itable at a negative offset. Avoid an ancestor table lookup if
source is a primitive type class.
(isInstance): Remove redundant isPrimitive() check.

of sync info object.
From-SVN: r42530

Jeff Sturm and Fergus Henderson.
* java/lang/ClassLoader.java: Remove dead code fragment.
From-SVN: r41876
* java/lang/natString.cc (_Jv_NewStringUtf8Const): Register finalizer.
Recalculate hash, since Utf8Const's hash is only 16 bits.
* java/lang/natString.cc (_Jv_StringFindSlot, rehash): Use high-order
bits of hash to calculate step for chaining.
* java/lang/natString.cc (intern, _Jv_NewStringUtf8Const): Rehash
when 2/3 full, rather than 3/4 full.
From-SVN: r41233
* java/lang/natString.cc (intern): If string's data does not point to
this String, make a fresh String that does.
* java/lang/natString.cc (unintern): Replace by static function.

From-SVN: r40990
* java/lang/natSystem.cc (init_properties): Get "file.separator",
"path.separator", and "java.io.tmpdir" from the File class, instead
of setting them explicitly.
* java/io/File.java: Do not canonicalize paths for security manager
checks. Call init_native() from static initializer. Do not pass path
argument to native methods. New native method declarations. Some
security manager checks moved to checkWrite().
(equals): Check file system case sensitivity and act appropriatly.
(hashCode): Likewise.
(isHidden): New method implemented.
(performList): Changed prototype. Now takes a class argument specifying
the class of the returned array: Strings or File objects. Also added

argument.
(stat): Handle ISHIDDEN query.
(isAbsolute): Remove WIN32 cruft.
(performList): New arguments. Handle returning either File[] or
String[] arrays. Check with FileFilter or FilenameFilter arguments as
appropriate. Use an ArrayList, not a Vector, for the temporary list.
(performSetReadOnly): New method implemented.

(performSetLastModified): Likewise.
(performCreate): Likewise.
(init_native): New initialization function.
* java/io/natFileWin32.cc: Various functions no longer take canonical
path argument.
(stat): Add FIXME about ISHIDDEN query.

* include/config.h.in: Rebuilt.
Resolves PR libgcj/1759.
From-SVN: r40985
* java/lang/natDouble.cc (parseDouble): Cannot use errno to
check for errors, since we don't want to throw exception on
overflow/underflow. Instead, trim whitespace, and then check that
_strtod_r uses up all the rest of the string.
From-SVN: r40800
* java/lang/natClass.cc (_Jv_IsAssignableFrom): Checking the
ancestors array is invalid for interfaces, so do that *after*
check that the target type is not an interface.
From-SVN: r40797
* java/lang/natClass.cc (_Jv_CheckCast): add class names to exception
* gnu/gcj/runtime/FirstThread.java (main): replace / with . in jarMainClassName
From-SVN: r40604

_Jv_AllocBytes returns zero'd memory. Use _Jv_AllocBytesChecked.
Use UNMASK_PTR.
(UNMASK_PTR): New macro.
(intern): Unmask pointer before returning it. Register finalizer
for the string.
(unintern): Handle case where
(MASK_PTR): New macro.

stackTrace buffer to a correctly aligned pointer array.
From-SVN: r40456
* java/lang/ExceptionInInitializerError.java (printStackTrace):
Only try to print the subordinate stack trace if "exception" is set.
Print our class name first.

* java/lang/Runtime.java (_exit): Declare new package-private native.
* java/lang/natRuntime.cc (_exit): Implemented. Same as exit() but
without a security manager check.
(exit): Call _exit after security check.

throws an exception, try to deal with it gracefully.
