    A thread was prematurely started during server startup and the
    thread was not cleaned up when a failure occurred. Also,
    threads were not stopped when the server was being torn down.
    

Problem conclusion

  • The problematic thread was altered to only start when it is
    needed, instead of during startup. This will prevent the
    condition where the thread is orphaned during a failed startup.
    The ServerFactory.stopServer() method will now also stop the
    thread when called.
