Sorry Tim, I don't know how to reproduce this issue. After this issue happened, I restarted AMQ broker by deleting the whole data directory. I have been observing AMQ logs, but haven't found this issue again.
Another point to note : Our app will try to subscribe again if subscription fails for any reason other than connection issues. It keeps retrying until it is successful or connection is down. This issue was observed with one specific topic "profile/specific_id" where specific_id is the ID of one specific user. From the logs backed up, I could see that this has failed for 250000 times (could have been more, but I had configured only 50 backup logs). After I restarted the AMQ broker, subscription was successful. I will keep observing and update if I find anything new. -- View this message in context: http://activemq.2283324.n4.nabble.com/ClassCastException-while-subscribing-to-a-topic-tp4710870p4711096.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
