Tested Message Queues
Open MQ
This open source message queue is tested in integration tests. It works perfectly.
Active MQ
This open source message queue is tested in integration tests. It works perfectly other than having a problem with temporary reply queues which prevents the use of JMSCacheLoader. JMSCacheLoader is not used during replication.
Oracle AQ
Versions up to and including 0.4 do not work, due to Oracle not supporting the unified API (send) for topics.
JBoss Queue
Works as reported by a user.
