• Increased default maximum heap size to 128MB and decreased default stack size to 64kB.
• Cleaned up internal handling of Unicode strings.
• Fixed getResources of bootstrap classloader.
• Correct handling of boot packages (provided glibj.zip contains a jar index).
• Exception handling fixes (don't allocate memory on Java heap).
• x86_64's code generator generates not RISC-style code.
• Green threads implementation removed.
• Semaphore implementation for Darwin (taken from Boehm).
• sem_wait interrupted by signal fixed.
• Overflow in Object.wait() (partially) fixed (caused busy waiting in JOnAS).

CACAO 0.95 released.

This is a bugfix release. Most important release features:

• Dead-lock bugfix. This should fix the random dead-locks seen in Eclipse or other applications.
• Search for suitable jar program during configure, can be specified via JAR environment variable
• --enable-zlib bugfix
• i386 bugfix: Set FPU to 64-bit on VM startup (fixes Debian bug #350729)
• powerpc bugfix: (M_COPY): Handle longs and doubles properly.
• Fixed instructions copying stackslots (like DUP_X1).
• Fixed classcache-related problem with java.lang.reflect.Proxy.
• Throw correct exception when trying to load a directory as a classfile (from a .zip file).
• Fixed incorrect method resolution when calling instance methods through JNI (fixes CACAO bugs #17 and #18).

CACAO 0.94 released.

Most important release features:

• support compilation of Interpreter and JIT compiler into one binary (not enabled by default)
• bootstrap ZIP code rewrite (VM startup time improvement)
• fixed JNI DirectByteBuffer functions, JOGL works now
• removed most third-party files from the repository, we link to the libraries instead
• removed VM interface Java files which were identical to the GNU Classpath upstream version
• added defineClassWithTransformers to java.lang.VMClassLoader, now we are able to build against the generics branch

• a lot of bugfixes

November 23, 2005

CACAO 0.93 released.

Most important release features:

• Java 1.5 support
• JIT codegenerators for Arm and MIPS (32-bit, -o32), currently closed-source
• integration of a vmgen-based interpreter (--enable-intrp)
• removal of GNU classpath, CACAO now uses upstream releases or CVS head versions
• finalizer thread
• JNI local references implemented
• reflection fixes and access checks (mauve tests)
• linear scan register allocator (-lsra)
• lazy resolving fixes
• fixed instanceof instruction
• updated to Boehm GC 6.6

July 14, 2005

CACAO 0.92 "Tomclipse" released.

Most important release features:

• runtime lazy-loading with code patching

• some ICMDs inlined (IDIV/IREM, LDIV/LREM, AASTORE, ARRAYCHECKCAST)
• register allocator uses unused argument registers
• stacktraces on MIPS, PowerPC and x86_64
• integration of GNU classpath's system class loader
• internal class loading code more Java VM Spec compliant (classcache, loading constraints, ...)
• virtual function table bugfix (abstract class implements not all interface methods)
• initial support for thread dump on SIGQUIT (<ctrl>-\) on most platforms
• GNU classpath 0.16
• Boehm GC 6.5
