I have discovered some problems with queues while running unittest in our own J2EE app.
After sending a message on a queue, when we try to call the close() method on the queue, we get the following exception:
org.apache.activemq.transport.TransportDisposedIOException: Peer (vm://localhost#69) disposed.
where the number after "localhost" is different every time.
We do not experience this problem with topics. We are using ActiveMQ as part of an "embedded" configuration with Geronimo.
I've done some debugging and the problem occurs at this line in the ActiveMQMessageProducer.close() method:
The queue itself is disposed properly in the dispose() method that is called in the line before, but this sending of the asynchronous packet fails.
