        Debuggee VM intermittently crashes when performing full collection of
        ParallelScavengeHeap.

        THE ISSUE APPEARS UNDER THE FOLLOWING CONDITIONS:

        1. Parallel or ParallelOld CG is used.
        2. VM_Thread is executing a Full GC operation. GC performs compaction on
           PermGen (i.e. there are dead objects there).
        3. At the same time there is a pending VM_ChangeBreakpoints operation in
           the VM operation queue which is intended to clear a JVMTI breakpoint.
