Ron Sigal commented on JBREM-1297:
----------------------------------
Hi Artur,
You did indeed find a deadlock. Thank you!
JBREM-1242 didn't really introduce the deadlock, but rather it caused the sequence
Client.setupClientLease() -> MicroRemoteClientInvoker.establishLease()
to acquire Client.connectionValidatorLock before acquiring
MicroRemoteClientInvoker.clientLeaseLock, which aligned it with the sequence
Client.addConnectionListener() -> new ConnectionValidator() ->
MicroRemoteClientInvoker.getLeasePinger()
What you discovered was another sequence,
ConnectionValidator$WaitOnConnectionCheckTimerTask.run() ->
MicroRemoteClientInvoker.terminateLease() -> LeasePinger.stopPing() ->
Client.notifyListeners()
which was misaligned with the other two sequences. The fix I used is essentially your
suggestion, except I synchronized on Client.connectionValidatorLock in
ConnectionValidator$WaitOnConnectionCheckTimerTask.run() instead of
MicroRemoteClientInvoker.terminateLease().

The fix is committed to branches 2.2 and 2.x. There is no specific unit test. Will watch
Jenkins for any anomalous behavior.

Hey Justin,
I've been getting some flaky runs on jenkins, which probably have nothing to do with
this issue, but I would like to see some reasonable results before I close the issue.
I'll run the test suites again today and see what happens.

One way to fix this would be to add lock on connectionValidatorLock in
MicroRemoteClientInvoker.terminateLease. I'm trying to analyse code to check if this
fix will not introduce another deadlock problem.

Hey Justin,
I'm getting some odd results in jenkins, which probably are completely unrelated, but
I want to look a little deeper. Sorry for the delay.

Ron Sigal resolved JBREM-1297.
------------------------------
Resolution: Done
Hi Justin,
Sorry about the delay. I ran the test suite again last week, and, despite some anomalies,
I don't see anything that would seem to be related to this issue, so I'm closing
it.
