Hi David,
It took some digging in the hs_err files and looking at a core dump to
determine what class
was being initialized.
I attached one to the current bug, there are others on the previous bug.
The "call_class_initializer" is the hook.

Please review a change to the Process reaper thread initialization to
preemptively
make sure classes ThreadLocalRandom and ConcurrentHashMap are
initialized.
I don't see ThreadLocalRandom appearing in any of the stack traces. ??

From the stack overflow failures, it seems that the classes have not
been initialized
before they are used during processing the termination of a process.
When the initialization is performed on the smaller reaper stack, it
occasionally
exceeds the available stack.
As an aid to diagnostics,
-XX:AbortVMOnException=java.lang.StackOverflowError
is added to TestHumongousNonArrayAllocation that has failed
intermittently.
If the problem happens again it will produce an hs_error file with
useful details
and will otherwise not change the test behavior.
