That exception can be caused when using the jboss-messaging-client.jar that ships with the jboss-messaging release. The jboss-messaging-client.jar contains a version of EDU.oswego.cs.dl.util.concurrent.ConcurrentHashMap$Segment that implements Serializable. However, the jboss app server contains a "concurrent.jar" that has a version of ConcurrentHashMap$Segment that does not implement Serializable. Replacing the version of lib/concurrent.jar with a version of concurrent.jar that contains a ConcurrentHashMap$Segment that implements Serializable will solve this issue. This situation occurs when you have a remote client that sends a message to a Queue. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
