  ****************************************************************
  When a trigger message is generated an attempt will be made to
  put it to the initiation queue specified. However if this cannot
  be successfully put, for instance if the initiation queue is
  full, the message is put to the dead letter queue, if defined.
  During the process of putting the trigger message to the DLQ,
  the MD passed to generate the dead letter message's MD is
  incorrect. This results in incorrect data in the MD for the dead
  letter message, which may also affect the expiry value,
  resulting in the message expiring at an unexpected time.
  

Problem conclusion

• Dead letter queue processing for trigger messages has been
  corrected, to ensure the correct MD fields are used for the MD
  of the dead letter message when it is put to the DLQ.
