  ****************************************************************
  When processing a message reference WMQConsumerShadow resumes
  the associated subscription, passing an option requesting a
  handle to the subscription's destination queue.
  If the subscription is a JMS 2.0 shared Subscription, CSQMSUBI
  incorrectly determines that the request is attempting to make
  the subscription non-shared, and returns MQRC 29440
  MQRC_SUB_JOIN_NOT_ALTERABLE.
  

Problem conclusion

• CSQMSUBI is changed to correctly handle this situation.
