After setting up the connection, session, and create a durable TopicSubscriber from within the MBean, I start a separate thread to perform the message receiving loop similar to the following:

while (true) {
Message msg = recv.receive();
processMsg(msg);
}

but the 2nd loop on the recv.receive() after the 1st message received, it encountered the following exception that I wonder people can shed some lights what's the issue here.

Thanks in advance.
