We're happy to announce that Jikes RVM version 2.2.1 is now available from
the developerworks website (
http://www-124.ibm.com/developerworks/projects/jikesrvm).
Highlights of this release include:
+ Jikes RVM is now based entirely on the GNU Classpath libraries. The
prior hybrid library solution is still supported in this release, but will
be removed in subsequent releases.
+ Jikes RVM can run a significant subset of the Eclipse IDE.
+ Separate name spaces for classloaders.
+ Implementation of JNI for Linux/PowerPC.
+ The addition of an on-stack replacement mechanism to enable the
adaptive system to transfer execution from long-running baseline compiled
frames and to recover from speculative optimizations. More details can be
found in a CGO 2003 paper.
+ Extensions for PowerPC hardware performance counters on AIX 5.
Other notes:
+ Future release of Jikes RVM will not support using the OTI class
libraries (hybrid library configuration).
+ We continue to anticipate moving completely to JMTk and removing
support for the watson collectors in a future release of Jikes RVM.This
should happen in the 2.2.2 release depending on the performance of the JMTk
MarkSweep collector.
A number of other miscellaneous bugs in version 2.2.0 are fixed in the
2.2.1 release. See the developerWorks bug tracking software tool and CVS
history for details.
