Description of problem: When you redeploy BRMS components (jbpm-human-task, business-central, business-central-server, jboss-brms), some threads are not cleaned up and keep live. Steps to Reproduce: (This is an example of business-central-server. You may test other components with similar steps) 1. Start brms-standalone 2. Login to http://localhost:8080/business-central/ 3. Capture a thread dump 4. Redeploy business-central-server.war (e.g. touch web.xml) 5. Login to http://localhost:8080/business-central/ 6. Capture a thread dump 7. Compare 2 thread dumps taken in step 3 and 6 Actual results: The number of threads increases. (You may ignore http threads) Expected results: The number of threads is not increased. (You may ignore http threads) Additional info: If you use BRMS components in Tomcat 7.0.42, Tomcat will log more clear messages for this issue so maybe useful to verify. ==== SEVERE: The web application [/business-central-server] appears to have started a thread named [Thread-0 (HornetQ-client-global-scheduled-threads-1981488825)] but has failed to stop it. This is very likely to create a memory leak. ====
