> Key: AMQ-3421
> URL: https://issues.apache.org/jira/browse/AMQ-3421
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.5.0
> Environment: Tomcat 6.0.29, Spring 3.0.5, Oracle Java 6, Centos 5
> Reporter: Robert Elliot
> Fix For: NEEDS_REVIEW

> Attachments: JStack Output.rtf, jmsMessageQueues.xml

> We are running a queue to do asynch audit updates, configured via Spring
> 3.0.5.
> When the queue fills up Tomcat locks up with all catalina threads waiting on
> an object monitor in Spring. This object monitor is held by the "ActiveMQ
> Connection Executor: vm://localhost#2986" thread which is itself blocked for
> ever awaiting the stopped CountDownLatch at
> TransportConnection.stop(TransportConnection.java:930).
> There are no "ActiveMQ Task" threads running, which suggests that either the
> task created by stopAsync has completed or did not run.
> A code review leaves us baffled as to how this latch cannot have counted
> down, but it hasn't. Could Tomcat possibly be silently discarding the thread
> that was meant to do the stop without throwing an exception?! It seems
> unlikely but (as I understand it) TaskRunnerFactory is breaking the Servlet
> spec by running up its own Threads.
