IT19650: The encoding message property was changed to value of 1 after being put onto a queue by a java application.

APAR status

• Closed as program error.

Error description

• A message that contains message properties was put onto a queue
  by IBM MQ classes for Java application. The message that the
  application was trying to put onto the queue had MQMD encoding
  set to 273 however when the message arrived on the queue, the
  encoding on both MQMD and RFH2 headers were set to default value
  of 1.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - The WebSphere MQ v7.5 classes for Java
  - The IBM MQ v8.0 classes for Java
  - The IBM MQ v9.0 classes for Java
  
  who are putting a message with message properties on a queue
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When putting a message that contains message properties onto a
  queue using IBM MQ classes for Java application , as a part of
  the put process, the application  re-encodes the whole message
  including its headers and body using a default encoding and
  CCSID. Therefore the message is not expected have the original
  CCSID and encoding after the put process. The default encoding
  was 1 however,  it did not describe fully how the numeric data
  (binary integers, packed-decimal integers, and floating-point
  numbers) in a message should be encoded.
  

Problem conclusion

• The IBM MQ classes for Java have been changed so that the
  default encoding is now 273 which describes the encoding for all
  three types of numeric data in a message.  This means the
  messages that are put into a queue will have encoding of 273 in
  MQMD and all subsequent headers such as RFH2.
