> Environment: Spring
> Reporter: skermani

>
> Hello,
> when undeploying a Spring (4) webapp (JDK 1.8.101), we got a memory leak
> error message on a thread.
> AVERTISSEMENT: The web application [venus] appears to have started a thread
> named [ActiveMQ InactivityMonitor Worker] but has failed to stop it. This is
> very likely to create a memory leak. Stack trace of thread:
> sun.misc.Unsafe.park(Native Method)
> java.util.concurrent.locks.LockSupport.parkNanos(Unknown Source)
> java.util.concurrent.SynchronousQueue$TransferStack.awaitFulfill(Unknown
> Source)
> java.util.concurrent.SynchronousQueue$TransferStack.transfer(Unknown Source)
> java.util.concurrent.SynchronousQueue.poll(Unknown Source)
> java.util.concurrent.ThreadPoolExecutor.getTask(Unknown Source)
> java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)
> java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
> java.lang.Thread.run(Unknown Source)
> oct. 20, 2016 2:50:43 PM org.apache.catalina.loader.WebappClassLoaderBase
> clearReferencesThreads
> when using an older version of active MQ 5.11.4 we don't get the error.
> We notice the shutwon of factory thread pool is not made anymore (
> inside class AbstractInactivityMonitor , method stopMonitorThreads
> this line has been removed: ThreadPoolUtils.shutdown(ASYNC_TASKS);
> Could you fix it.
