Local fix

Problem summary

  • Thread hang when CICS/WAS application(using JNIReaderPool) makes
    an EJB request using the ORB. This is due to the Connection not
    moving to ESTABLISHED state.An outgoing new request is waiting
    forever for the Connection to move to ESTABLISHED state.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR11
    5.0.0 SR14
    .
    The ORB has been fixed to move the Connection to ESTABLISHED
    state prior to the Reader Thread getting created.
    

Temporary fix
