David, Doug,
This test has been failing intermittently on jdk7u-dev and jdk8 for a
while now. It only appears to fail when run in our internal build/test
system (JPRT).
I believe the cause of the failure to be simply that the machines the
test is run on are too slow, or very busy, and the defensive timeout in
the test are not large enough to handle this. The solution is to
increase these timeout (similar to other tests in the concurrency area
that we increased the timeouts for too).
