JMS Listener not catching MQHRF2 Messages from MQ
You were able to get the JMS Listener to receive messages from MQ Topic before when using MQSTR, but now a new Topic is not yielding messages to their JMS Listener because its being sent from .net client and using MQHRF2 format
Steps to Reproduce
Send different types of messages to the JMS Listener.
Calling program was using un-supported MQHRF2 format.
Change your client calls to use the supported MQSTR format.
MQHRF2 is not supported because it is not part of the JMS specifications. It is part of a third-party implementation of MQ.
