Hi all! Jato 0.2 release is now available! Jato is an open source, JIT-only virtual machine for Java that aims to support the latest JVM specification. It can currently run many Java applications on 32-bit x86 Linux machines such as Eclipse. What's new in this release: - Jython and JRuby start up under the VM (requires GNU Classpath CVS HEAD) - Annotation support (Pekka Enberg, Nikhil Sarda) - More missing JNI APIs implemented (Joonas Reynders, Nikhil Sarda) - More missing reflection APIs implemented (Nikhil Sarda) - Linux/x86-64 port fixes (Eduard - Gabriel Munteanu, Sergey Mashkov, Pekka Enberg) - Linux/i386 bug fixes (Tomek Grabiec, Vegard Nossum) - SSA form bug fixes (Ana-Maria Farcasi) - Darwin port fixes (Michael Tremel) NOTE NOTE NOTE! You're strongly encouraged to use GNU Classpath CVS HEAD because it has important Jython and JRuby compatibility fixes that are not part of any release. There's a Github mirrof the GNU Classpath here for people who don't want to use CVS: https://github.com/penberg/classpath The source code for Jato is available for download here: http://www.kernel.org/pub/software/java/jato/jato-0.2.tar.bz2 You can also get the latest sources from the git repository: git clone git://git.kernel.org/pub/scm/java/jato/jato.git If you have questions, comments, or suggestions, feel free to drop by at #jato on irc.freenode.net or send an email to our mailing list at: http://groups.google.com/group/jatovm?hl=en You can also report problems on Github: https://github.com/penberg/jato/issues For more information, please check out the Jato home page: http://www.jatovm.org/ Pekka --- Changes from v0.1.1 to v0.2: ---------------------------- Ana Farcasi (3): jit: fix initialization of a compilation unit test/unit: Added test for dominance frontier sets arch/x86: Fix print_jmp_memindex Ankit Laddha (1): arm: Add dummy functions to make Jato link on ARM Balagopal (1): vm: Add option -Xtrace:vtable for tracing all vtables Eduard - Gabriel Munteanu (9): x86-64: fix unwind emitter Add DEBUG option to the build system.
