What's changed in IBM MQ 9.0.0 Fix Pack 4

IBM® MQ 9.0.0 Fix Pack 4 includes a number of changes to functions and resources.

Changes to fteModifyAgent and fteModifyLogger commands

From IBM MQ 9.0.0 Fix Pack 4, additional checks are added under APAR IT22423 such that any updates that are made to the JVM options for an agent or logger with the -serviceJVMOptions parameter of the fteModifyAgent or fteModifyLogger command are verified to make sure that the options have been correctly specified. For more information, see Guidance for updating agent or logger JVM options.

Javadoc information update for the MQMessage.writeString(String) method

The Javadoc information for the MQMessage.writeString(String) method has been updated as follows:
Writes a String into the message buffer at the current position, 
encoding it using the coded character set identified by characterSet.
If characterSet is set to the default value of MQCCSI_Q_MGR,
then the coded character set used to encode the String depends on
the platform that the application is running on:
- If the application is running on z/OS, then the String will be 
encoded using coded character set identifier 500.
- For all other platforms, the String will be encoded using coded 
character set identifier 819.
