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
