  * RECOMMENDATION:                                              *
  ****************************************************************
  When attempting to get grouped messages from a shared queue and
  specifying MQGMO_ALL_MSGS_AVAILABLE, an internal reference to
  the message data may not be correctly initialized and as a
  result, can prevent the MQGET from succeeding.
  

Problem conclusion

• Processing has been amended to ensure the internal pointer to
  the message data is correctly initialized.
