Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V9.0 on z/OS using the JMS 2.0 API   *
    *                  and the MQ JMS messaging provider.          *
    ****************************************************************
    * PROBLEM DESCRIPTION: When using client-then-bindings         *
    *                      transport mode, a ClassCastException    *
    *                      can be thrown when calling              *
    *                      createContext()methods.                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If a bindings connection is possible then a ClassCastException
    can be thrown on z/OS. This is because the initial underlying
    MQ connection process succeeds, but this then drives code that
    creates a JMS Connection instead of a JMSContext object, which
    in turn causes the ClassCastException when the
    JMSContextHandle is created to hold it.
