New JRE and HDK Snapshots Posted
Our latest snapshots have
lots of new fixes and features. The VM has a new GC,
almost complete JVMTI, and now can co-exist with
the IBM® VME in
the Harmony JRE structure. Our classlibrary continues to grow with new
classes, notably CORBA, thanks to
Apache Yoko.
Also, the classlibrary includes many new fixes and updates.
Choose the JRE to test your favorite applications, and
give us feedback on how
we are doing, or use the HDK to enable faster development of the Harmony classlibrary.

VM Interface and Core Classes Contribution
IBM has offered the Apache Harmony project a set of core
Java classes and an implementation of a VM/class library
interface. Tim Ellison wrote:
"I'm delighted to be able to make a code contribution to the
Harmony project on behalf of IBM. The code comprises a concrete implementation
of the interface between virtual machine and class library that we have
been discussing recently, together with a set of core Java classes."
This contribution is sufficient to run Ant and the Eclipse Java
compiler, to provide a basic self-hosting environment. IBM also
made a version of their J9 VM
available for use by the project in evaluating this contribution.
Thanks Tim and IBM :) (2005-11-08)
