This issue is still creeping me out.
First of all, I'm perfectly fine with your workaround.
OK, good to hear. Thanks.
Nevertheless, we should probably create an app that produces the
IllegalMonitorStateException and deliver it to the Java developers. If
this is a Java bug - and I have no other explanation - then it's a
really critical one...
Although I do not have the time to work on this myself, I support your
initiative.
Hint taken. ;)
My only problem is that I don't have any system that's able to
reproduce this bug (only Mac or Linux) and I'd rather not want to
submit this already very obscure issue without being sure that the
attached example/application is really reproducing the problem.
On the lbcore224 branch before commit eef137b0c6ca92cd4 [1], running
on Windows 7 64 bits and AMD Phenom II X4 965 processor, I am able to
reproduce the bug 6 or 7 times out of every 10 runs. So it's pretty
reproducible, at least on my machine.
The fact that the IllegalMonitorStateException is thrown within the
ZooKeeperServer.shutdown method could be relavant. I was also
wondering whether the IllegalMonitorStateException could be caused by
Thread.interrupt calls.
