Really awesome, BEA, this will be very helpful to Harmony developers!

Some background:

Modularization is one key objective of Harmony project, and it is key enablement tocommunity innovation on Java SE technology. Harmony class library is separated to 20+ modules, and JVM/Classlib is also decoupled by a well designed VMI(Virtual Machine Interface), JVM implementation is "compatible" with Harmony(i.e., can work with Harmony class library) as long as it implements this VMI, which includes several native APIs as well as 23 Java classes, besides standard JNI and JVMTI. Harmony is also trying to provide a Classpath adapter to work with GNU Classpath compatible JVM.

Currently there are several JVMs supporting Harmony VMI. JRockit is the second production VM, after IBM J9 VM, the light weighted SableVM and Harmony's own DRLVM are open source alternatives.
