After the fix for 4846970, the same test case hangs as follows (Takes 2-3days):
Two threads ( xxxxx@xxxxx , xxxxx@xxxxx ) encounter simultaneous out_of_bounds exceptions, 1 ( xxxxx@xxxxx ) gets the classStructureMonitorEnter lock and proceeds to wait for GC,
the 2nd ( xxxxx@xxxxx ) is hung in lwp_mutex_lock with SIGUSR2 disabled,
and so we never successfully suspend for GC.
