JMS Race condition - session close?

[gmccreath]

All,

I get the following on my test server reasonably often:

18:08:54,797 WARN [SpyMessageConsumer] Message consumer closing due to error in listening thread.
javax.jms.IllegalStateException: Session is closed.
at org.jboss.mq.SpyMessage.doAcknowledge(SpyMessage.java:604)
at org.jboss.mq.SpyMessageConsumer.run(SpyMessageConsumer.java:562)
at java.lang.Thread.run(Thread.java:536)

I am stopping the connection and closing the session and connection *immediately* after receipt of my test message from the client.

Not closing/stopping solved the problem (but it not a solution). Race? How do I ensure acknowledgements happen correctly?

Many thanks,

Greg.

consumer.close() will ensure the background thread has completed its
processing (acknowledgement).
The close will wait for the background thread to stop.

The problem with closing the connection is that it tags the connection/session
as closed to avoid further use of them during the close.

Many thanks for that.

That's got it.
