IV93480: MQ V8 XMS FAILS TO CONSUME MESSAGES WHICH CONTAIN AN RFH2 HEADER WITH USER DEFINED PROPERTIES CONTAINING ATTRIBUTES

APAR status

• Closed as program error.

Error description

• XMS.NET applications throw an error while receiving a message
  which contains an RFH2 header with user defined properties
  containing attributes.
  
  The following Exception is being thrown during the processing of
  the RFH2 usr folder
  
  CWSMQ0286E: An internal error occurred within method
  ParseFolderToPropertyNodes(StringBuilder). Malformed WMQ message
  content <Dlv context="none" dt="string"></Dlv><Dst
  context="none" dt="String"></Dst><Tms context="none"
  dt="string"></Tms> was detected.
  

Local fix

• Remove the attributes (context="none" dt="string")from the
  header pages. The XMS application is then successfully able to
  read the  message.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All the XMS.NET applications receiving a message,which  contain
  any other attribute in its RFH2 "usr" folder other than "dt"
  will fail to receive the message.
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  XMS.NET Code expects only attribute of type "dt" in the RFH2's
  usr folder.If there is any other attribute defined the following
  exception is thrown.
  
  CWSMQ0286E: An internal error occurred within method
  ParseFolderToPropertyNodes(StringBuilder). Malformed WMQ message
  
  If any additional attribute other than "dt" is added the
  following form
  <Dlv context="none" dt="string"></Dlv>
  
  then Parsing of the message fails with CWSMQ0286E error code.
  

Problem conclusion

• The parsing code has been changed to ignore any other attribute
  other than "dt" rather than throwing an error.
