Problem - Seems like the client classes are still being deployed at runtime in eclipse. That problem seems to have gone away when I turned off dynamic marshallers. Here is the stack trace from socialpm:

Hmm, from this stack trace it looks like the client classes are not being deployed to the app server (hence the ClassNotFoundException), but for some reason the server-side CDI event dispatcher has received a (client-local) LogoutEvent from the client. I guess that means that either the server-side EventDispatcher has subscribed to that message subject, or the client bus made a bad routing decision in sending that event to the server.
Can you list out your subscriptions in the JavaScript console, or use the bus monitor app? That might give us a clue about which scenario we're dealing with.
