• In rare circumstances, aborts of global units of work
  involving MQGETs of messages greater than 52k will result in an
  abend of the primary queue server responsible for the queue.
  This renders the queue manager unresponsive
  

Problem conclusion

• A defect in tidying up transaction context results in an attempt
  to reference a null pointer. The code has been amended to
  exclude this path in the event that the pointer is null.
