Maybe that's okay for the time being, but being able to deploy an updated version of your application without any downtime might be a desirable feature. - -chris >>> 17-Apr-2020 08:44:41.745 WARNING [main] >>> org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThre ads >>> The web application [Kiss] appears to have started a thread >>> named [Thread-5] but has failed to stop it.

The proper solution is in your log: "The web application [Kiss] appears to have started a thread named [Thread-5] but has failed to stop it." If that's not a daemon thread, the JVM, by design, can't stop. Instead of calling System.exit(), do the right thing and implement proper shutdown for all threads that the application starts on its own. Or, if you don't care about interrupting them at inopportune time (as you demonstrate with System.exit), simply set their daemon flag and leave their buggy implementation in place. By the way: This behavior will keep the application from proper redeployment. My recommendation: Correct your implementation rather than nuking it from orbit.

I suppose, never mind. I created a startup listener that just does a System.exit(0) on contextDestroyed which is what I want - exit. Thanks.
