Fix Pack 7.1.0.6 for WebSphere MQ V7.1

APAR status

• Closed as program error.

Error description

• XMS is not moving the poison message to the BACKOUT queue when
  the message is encountered and it exceeds the backout
  threshold. This causes the IBM.XMS libraries to generate the
  following error:
  
  <Message>WCFCH0316E: A failure occurred while processing a
  poison message...The message has been backed-out to the request
  queue and the channel faulted, no further messages will be
  received.
  The action requested in the report options for the message did
  not complete successfully, the message or report could not be
  delivered to the backout queue, reply queue, or dead letter
  queue.
  Review the linked exceptions and trace for further details of
  why the
  processing failed. Once the cause of the failure has been
  rectified,
  the channel must be re-started to continue operation.</Message>

  PROBLEM DESCRIPTION:
  XMS.NET Applications while moving the poison messages to the
  backout queue throws NullReferenceException
  

Problem conclusion

• While Parsing DstnUriParser parameter,the application throws
  NullReferenceException.If there is a change in the destination
  URI then only XMS should get the new URI Parser, otherwise it
  shouldn't be doing. Though there is no change in the URI, XMS is
  still trying to get the new URI Parser, which is Null,due to
  which the exception is being thrown.
