I *think* this failure is related to the recent integration of:

    JDK-8270085 Suspend during block transition may deadlock if lock held

So far this failure has only been since once on Windows and
it did not show up in my stress testing of JDK-8270085 prior
to integration. Since this is a (possible) regression, I'm starting
this bug at P2.
