-------------------------------------------

FYI: when I remove BecomeServerTest from the byteman ant target, the other byteman tests pass on the same host:

> Running the Byteman tests in the QA lab, this test deadlocks in a repeatable fashion and causes the testsuite to hang.
> The test makes use of the Byteman rendezvous built-in function to suspend (and reorder) thread execution. It appears that with threads re-ordered, certain parts of JGroups block in such a way that no progress is made and the test deadlocks.
