I have a service that listens to and services JMS queues. I have been starting and stopping it and have been watching the thread count grow. Through a tedious trial and error session I have determined that the thread that is produced when javax.jms.Session.createConsumer() never goes away. I am calling MessageConsumer.close() but the thread stays around. Even after I undeploy my service the thread that was created by it remains. I did this by remote debugging my JBoss server using eclipse and looking at the threads. I even wrote a simple test program that crated a consumer then closed it and I stepped through it watching it create the thread. When I stepped through the close method it di ot go away. Has anyone else seen this? This is a huge show stopper for us, as this won't run like this too long before all the resources are exhausted.
