No, the test is single-threaded.

Multi-threaded version is easy to create, but I don't see much sense in
it now, until a single-threaded test starts to pass stably. Also,
multi-threaded test crashes would be more difficult to analyze.

Yes, I have reduced the test, looks like the problem is not in mass
class loading, but in org.mmtk.plan.Plan class itself. Both RI and DRLVM
terminate without catching exception that occurs on this class's
initialization. Really strange.

See http://issues.apache.org/jira/browse/HARMONY-2650

does it run in multiple threads (for better stressing:)?

interesting!
could you, please, reduce the test?
