Could you check the version of jboss-remoting.jar in server/default/lib of your JBoss Application Server installation. [Substitute your configuration for "default".] An easy way to find the version is to run the jar: | java -jar jboss-remoting.jar | This sounds like a problem that existed in earlier versions of the bisocket transport, but which has since been fixed.
