Thread leak in WorkQueueManagerImpl and AutomaticWorkQueueImpl when we use it
in tomcat
---------------------------------------------------------------------------------------
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
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}
David
