AddNotificationListener is serializing the handback object to the server -- causing ClassNotFoundExceptions. ------------------------------------------------------------------------------------------------------------ Key: REMJMX-91 URL: https://issues.jboss.org/browse/REMJMX-91 Project: Remoting JMX Issue Type: Bug Components: Notifications Affects Versions: 2.0.1.CR1 Reporter: Bryan Varner Assignee: Darran Lofthouse Fix For: 2.0.1.CR2 I have a client using a handback object when events are received from remote JMX servers. The handback is a local object instance used in the client, and should be operated on as part of handling specific types of notifications. Rather than scoping this thing in my code all over the place, it was much easier to include it as a handback. This works _perfectly_ with the Oracle RMI client. When I try to use this code against JBoss remoting servers, I get (burried) ClassNotFound Exceptions referencing the name of my class. It appears that ClientConnection is sending serialized copies of the handback object to the server when a notificationListener is added... but why? https://github.com/jbossas/remoting-jmx/blob/master/src/main/java/org/jbo... Shouldn't the handback be local to the client?
