Local fix

Problem summary


    

  • ****************************************************************
USERS AFFECTED:
User of the IBM MQ JMS for Java.


Platforms affected:
MultiPlatform

****************************************************************
PROBLEM DESCRIPTION:
The current IBM MQ JMS for Java use the whitelist property names
that defines which Java classes might be serialized with
ObjectMessage.setObject() and deserialized with
ObjectMessage.getObject().

    



Problem conclusion


    

  • The code has been update to change the use of allowlist property
name as well as whitelist.

Also added new property values:
com.ibm.mq.jms.allowlist.discover - This property behaves the
same as the existing property com.ibm.mq.jms.whitelist.discover.
com.ibm.mq.jms.allowlist.mode - This property behaves the same
as the existing property com.ibm.mq.jms.whitelist.mode.
com.ibm.mq.jms.allowlist - This property behaves the same as the
existing property com.ibm.mq.jms.whitelist.
