• Closed as program error.

Error description

• When DataPower  processes messages containing  MQJMS headers
  within a transaction and this transaction fails, the messages
  are not moved to the backout destination.
  This issue happens  only  when  the Front side Settings
  instruct to remove the MQRFH2 header.
  After reaching the defined threshold value the message  will
  enter an endless loop  failing to enter the backout
  destination.
  

Local fix

• None
  
  Possible workaround outside DataPower: Remove  the  java JMS
  header on sending side before transmitting to DataPower.
  

Problem summary

• When the appliance rolls back MQ messages, it might fail if MQ
  front side handler removes any MQ headers.
  

Problem conclusion

• Fix is available in 7.0.0.18, 7.1.0.15, 7.2.0.12, 7.5.0.6,
  7.5.1.5 and 7.5.2.3
