Jato 0.0.2 released

Hi all!

I'm proud to announce the release 0.0.2 of Jato!

Jato is a JIT-only virtual machine for Java that can run some Java applications
under GNU/Linux on modern 32-bit x86 CPUs that support the SSE2 instruction
set. A port to the x86-64 machine architecture is currently being developed.
Jato depends on GNU Classpath to provide core Java runtime classes. The VM is
licensed under the GPLv2 with GNU Classpath linking exception.

You can download the full source distribution at at the following location:

  http://www.kernel.org/pub/software/java/jato/jato-0.0.2.t...

or fetch the latest sources from the git repository:

  git clone git://git.kernel.org/pub/scm/java/jato/jato.git

This release has bunch of fixes to make some new programs run under Jato:

  - Java Tris: http://bit.ly/7wrE4H

  - Clojure REPL: http://clojure.org/

  - DaCapo: http://www.dacapobench.org/

There's also lots of infrastructure work for garbage collection (not functional
yet) and fixes to the x86-64 port (also not fully functional).

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:
