Are you able to shut down the daemon thread at application shutdown? If you can get a handle to the thread, use a servlet context listener contextDestroyed() method to do the shutdown. The classloader can't be destroyed properly when a daemon thread is still running within it. I don't pretend to know the details of the destruction of the WebappClassLoader, so I'll leave the specifics to someone who knows better.
