  • Closed as program error.

Error description

  • When attempting to stop a application server on WPS for z/OS the
    servant shuts down, but not completely as there is a remaining
    hanging thread.
    
    The reason for this is that a JMS connection is trying to be
    closed on a finalize block while the messaging engine is already
     stopped.
    
    So the close call never returns.

Problem summary

  • When attempting to stop an application server on WebSphere
    Process Server for z/OS the servant shuts down, but not
    completely as there is a remaining hanging thread.
    The reason for this is that a JMS connection is trying to be
    closed in a finalize() method. This happens when the messaging
    engine is already stopped and as a result the close call never
    returns.
    The JMS connection is designed to stay open as long as the BPEL
    engine is alive, because the connection is used in system
    failure scenarios.
    

Problem conclusion

  • When running on z/OS the JMS connection is no longer closed in
    the finalize() method.
    

Temporary fix
