[jira] Created: (UIMA-1439) Fix interemittent hangs in UIMA AS when
stopping the JMS listener
Fix interemittent hangs in UIMA AS when stopping the JMS listener
-----------------------------------------------------------------
Key: UIMA-1439
URL: https://issues.apache.org/jira/browse/UIMA-1439
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
When stopping UIMA AS listener, the ThreadPoolTaskExecutor shutdown method is called and the code than waits for all threads managed by the executor to stop. The problem is that listener's stop method may be called from one of the threads that are being managed by the executor. The executor tries to stop the thread and the thread tries to stop the executor. This leads to a hang.

-------------------------------
Resolution: Fixed
Fixed under JIRA UIMA-1433. Bug in caching JMS connections prevented cleanup code from stopping AMQ threads.

[jira] Reopened: (UIMA-1439) Fix interemittent hangs in UIMA AS

Jerry Cwiklik reopened UIMA-1439:
---------------------------------
Fix a hang in the service listener that prevents the listener from stopping. ActiveMQ Scheduler threads dont seem to stop and the code that checks for active threads is waiting for them to stop.

Jerry Cwiklik commented on UIMA-1439:
-------------------------------------
Modified destroy() method of the UIMA AS listener to shutdown the ThreadPoolTaskExecutor and than check for number of active threads. Since the thread the initiated call to destroy() maybe one of those managed by the executor allow for one active thread when determining if the executor is shutdown.
