Hi,
Please help to review the fix for bug
https://bugs.openjdk.java.net/browse/JDK-8004807 as below:
http://cr.openjdk.java.net/~ewang/JDK-8004807/webrev.00/
The root cause of the failure is if Timer.cancel() is not called in
time, the recurring timer task keeps running which cause the the
assertion "check(latch.getCount() > 0)" failed.
The fix includes:
1. As the purpose of the assertion "check(latch.getCount() > 0)" in
timer task is used to check if the unrepeatable task is executed
repeatedly and this assertion is meaningless for a repeatable task. it
can be replaced by other way, see the webrev.
2. The timer thread should be terminated ASAP once all tasks are
finished to avoid time spent on thread switch.
3. The test should be executed in othervm mode to avoid time spent on
thread switch.
Thanks,
Eric
