It's been almost nine months since the release of Jikes RVM 3.0.1, and quite a bit has changed in Jikes RVM. We'd like to call out several items that may be of particular interest to the community.

1. Jikes RVM has switched to using native threading instead of m-to-n (aka green) threading.
2. The default mature space collector has changed from Mark-Sweep to Immix.
3. Jikes RVM is now licensed under the Eclipse Public License (EPL).
4. The 3.1 release significantly improves over the performance of 3.0.1, with speedups of 10% and 21% on average for DaCapo and SPEC benchmarks respectively on an Intel C2Q. Highlights include a 29% improvement in jbb and a 32% improvement in jython.... read more

We're very happy to announce a new release of Jikes RVM: version 2.9.0. Quite a bit has changed since 2.4.6 and we'd welcome feedback on the changes as we head towards a 3.0 release later this year.

to prepare for making it easier to develop Jikes RVM using Eclipse.
All files except for the Java source to Jikes RVM itself was moved
out of the RVM_ROOT/rvm directory. RVM_ROOT/rvm itself has not yet
been reorganized so that package/directory structures match, but we
anticipate this happening in the near future.... read more

The Release Notes are appended below.

*Highlights
** OS X is working again.
Support for running Jikes RVM on OS X has been restored.

** Major MMTk Refactoring.
The most significant refactoring to MMTk since the initial release has
been completed. The MMTk Plan class hierarchy has been split to more
clearly distinguish global and local state, and move toward a more natural
Java style. This has involved substantial changes to the plan hierarchy,
which is now structured a set of subpackages under org.mmtk.plan. For more
information on the MMTk refactoring please refer to the tutorial and
cheatsheet in the MMTk/doc directory, both of which are intended to
assist with users migrating collectors to the new release.... read more

I'm very happy to say that the final step in making Eclipse work seamlessly with MMTk was completed today. You can point Eclipse at the $RVM_ROOT/MMTk directory and you should find that it works seamlessly without errors. There is now a .classpath file in the MMTk root directory which tells Eclipse where to find the various classes (the org.mmtk.vm stubs and the org.vmmagic stubs are in a new "ext" directory now). This is in cvs now and will appear in the next release.... read more
