Testing the java memory model, and hence threading, is really tricky and all I can think right now is some testing stuff Doug Lea released regarding to java.util.concurrent. What I know is that a test to be worth something, it must be done in a SMP machine. HyperThreading helps a little, but in a UP setup getting the JMM right is a lot easier.
For the rest I strongly suggest using Mauve, it can test a lot of the classlib and would be nice to have only one FOSS testsuite for classlibs. For conformance of the JVM I think something simpler should be used, just a way to call static methods of defined classes and gather the result - no JNI used. Given that we could write very small tests that could focus on specific implementation details. I can write a prototype of such tool for bootjvm.
