Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using MQ .NET application to read Reference Message from a
  queue (messages with MQRMH header).
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When the MQ .NET client read a reference message, it incorrectly
  parsed part of the MQRMH header as an RFH2 header. As the format
  of these headers is different, this was incorrect, and caused an
  IndexOutOfRange exception to be reported.
  

Problem conclusion

• The MQ .NET client has been updated to correctly process the
  MQRMH header.
