  ****************************************************************
  During a transaction commit call the return of XAER_RMERR
  indicates an error with the resource preventing the commit
  from completing. Such problems usually require manual
  intervention to fix. If a remote resource manager is
  unavailable XAER_RMFAIL should be returned to indicate this
  and that retrying the commit later may succeed.
  
  The default messaging provider returns XAER_RMERR when the
  connection to the remote messaging engine has failed.  This
  situation should return XAER_RMFAIL as a later retry when a
  connection is available will likely succeed.
  

Problem conclusion

• This fix changes the return code during a failed commit to
  XAER_RMFAIL if the connection to the messaging engine failed.
