Jikes RVM 3.0.0 released

We're very happy to announce the release of Jikes RVM version 3.0.0.
The road towards 3.0 began just about two years ago and a large number of
people, both on the core team and from our user community at large,
have contributed to making it a success. Thank You!

The release is available for download at http://downloads.sourceforge.net/jikesrvm/jikesrvm-3.0.0.tar.bz2

The detailed release notes for major changes since 2.9.3 can be found
below or in JIRA (http://jira.codehaus.org/browse/RVM/fixforversion/13530),
but we'd like to highlight some of the larger themes that went
into the 3.0 release (many of which have already been released in
the 2.9.x releases we've made along the way).
Normalization of source code and build process
Complete rewrite of the build/test systems to use ant.
Jikes RVM can be developed in Eclipse using the JDT
Extensive restructuring of package structure
Removal of VM_ and OPT_ prefixes from all source files.
Increased system stability and performance
A new continuous testing system (http://jikesrvm.anu.edu.au/cattrack)
Concerted stability and performance drives
** Java 5 support
Support for Java 5 language features
Use of Java 5 language features throughout the code base
