I haven't looked in the new Spring code, but if it's still creating a new consumer to receive each message, then, *even if you're using a JCA JMS resource adapter* (e.g. JmsXA in JBoss), that is not safe!

The resource adapter will only cache sessions, not consumers. So a new consumer will still be created each time. That means, on a topic with a non durable subscriber, any messages that arrive between one consumer and the next, will appear to be lost.

Also each consumer is likely to cache a bunch of messages, so every time you close one they have to be rolled back to the queue.

==> Horribly slow + "Lost" messages
