PH16310: MQ ABEND5C6 00D40025 , LOC=CSQILPLM . CSQMHDRS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Hursley finds from the documentation that the abend is
  occurring while doing an MQGET for a message. An MQRFH2 header
  is found and data conversion is attempted. In processing the
  header we need to convert the 8-byte MQRFH2->Format field but
  it contains invalid characters. When we attempt to convert the
  header the resulting string exceeds the maximum length of
  8-bytes and we fail to report this to the caller in an
  appropriate manner and abend instead. This results in an abend
  5C6-00D40025 occurring in CSQMHDRS when getting the message.
  
  This APAR intends to amend the code to more gracefully handle
  the invalid Format field in an MQRFH2 header. Note that even
  with the fix in place, an error will still be seen until any
  invalid contents within MQRFH2->Format field are addressed.

  ****************************************************************
  The code which deals with the conversion of the format field
  when converting from message properties to an RFH2, was not able
  to gracefully handle a format field that contains invalid
  characters that expand during conversion.
  

Problem conclusion

• The code has been changed to instead return the RFH2 header in
  the CodedCharSetId of the previous header.
