> Key: CXF-3614
> URL: https://issues.apache.org/jira/browse/CXF-3614
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.4.1
> Reporter: David Liu
> Assignee: Willem Jiang
> Fix For: 2.3.6, 2.4.2, 2.5

> Hi,
> There is the threadleak in WorkQueueManagerImpl / AutomaticWorkQueueImpl
> when we use it in tomcat or other web container. In AutomaticWorkQueueImpl
> created by WorkQueueManagerImpl, it has a class WatchDog which is a daemon
> thread, If we call shutdown in WorkQueueManagerImpl, it only clean the queue
> in AutomaticWorkQueueImpl but it won't notify WatchDog thread, so the
> WatchDog will wait and live until we exit JVM.
> It won't cause issue if we run CXF as standalone app, however, it will
> cause thread leak in tomcat because we do not stop tomcat when we undeploy
> cxf web-app, so we cannot destroy WatchDog thread in this case.
> Could you please fix it? thanks.
> {code}
> public class MyWorkQueueManagerImpl extends WorkQueueManagerImpl implements
> DisposableBean {
> @Override
> public void destroy() throws Exception {
> this.shutdown(false);
> for (AutomaticWorkQueue queue : namedQueues.values()) {
> if (queue instanceof AutomaticWorkQueueImpl) {
> AutomaticWorkQueueImpl queueimpl = ((AutomaticWorkQueueImpl)
> queue);
> queueimpl.terminated();
> queueimpl.watchDog.interrupt();
> }
> }
> }
> }
> {code}
