TEST PASSED
----------System.err:(3/38)----------

JavaTest Message: Test complete.

result: Error. Agent error: java.lang.Exception: Agent 5 timed out with a timeout of 3000 seconds; check console log for any additional details

Please note that the test passed while the timeout handler was
running. The test executed for 78 minutes:

elapsed time (seconds): 4706.187

which is a pretty long time. The test is invoked with:

    run driver/timeout=300

and the typical timeoutFactor is 4 so this test should have
run for (4 * 300) => 1200 seconds before timeout. Instead
we see this:

Timeout refired 3000 times

which indicates that that the timeoutFactor is 10 for this
test task. Normally, I would check the task's log file, but
the test task is showing a state of "SCHEDULED" so I
think the test task is being rerun (for some reason).

Starting this bug off in hotspot/compiler since this is a
"jit/escape" test.
