Right, once the main thread completes then jtreg will attempt to cleanup
the remaining non-daemon threads in the thread group. It does this by
interrupting each of the remaining threads in a loop up to a maximum
number of rounds or until the remaining threads have terminated. It's
possible that if the test is changed up to join on each of the 3 threads
that this intermittent failure will go away. If so, then it suggests to
me that perhaps the interrupt is causing a side effect that causes one
of the threads to go into a loop block uninterruptedly. This is just a
guess of course and it requires digging into the Locale code to come up
with specific theories.
