> 1. Connect a JMS Topic Subscriber with limited memory (e.g. -Xmx64m), that buffers an infinite number of messages.
> 2. Publish messages to JBM, on the same subscribed topic, until the client runs out of memory.
> 3. Try to connect another client, publish more messages, etc. You should see the problem at this point.
> 4. Kill the OOM client. The system should recover.
> 5. at this point, the JBM server gets hanged
