setDaemon(true) will cause the thread to exit on shutdown, but will it cause the thread to exit when the MBean is stopped or undeployed?
We just implemented logic in the stop() method to interrupt the threads so they will exit when JBoss stops the MBean.

Default is false and then the thread just lives on.
