Replication of EJB Session Beans does not work in cluster

                 Key: WELD-863
                 URL: https://issues.jboss.org/browse/WELD-863
             Project: Weld
          Issue Type: Bug
    Affects Versions: 1.1.0.Final
         Environment: JBossAS 6 SNAPSHOT (from 2011-03-02) - built in hudson
            Reporter: Martin Gencur
            Assignee: Ales Justin
             Fix For: TBC
         Attachments: weld-translator.ear

I tested this feature with JSF/Translator example and I needed to do a few changes to test this feature. My fork of weld-core with the changes can be found at: https://github.com/mgencur/core/tree/cluster-test. I'll also attach a packaged ear of the app which I used.

Steps to reproduce the bug:

1) deploy the attached weld-translator.ear file or checkout my changes from github and build the application
2) start first and second instance of the JBossAS to create a cluster (can be found at https://github.com/weld/core/blob/master/examples/README.md)
3) deploy the app
4) go to your web browser and disable cookies
5) go to http://localhost:8080/weld-translator, enter some text and click "Translate"
6) now change the port number in the address to 8180 and refresh (note that there should be also jsessionid included in the URL)
7) now the text you entered into the text area should be still there (since the value is stored in a field of SFSB which is clustered, but instead, you get the following exception at the slave JBossAS instance:

12:00:16,662 WARN  [org.jboss.web.tomcat.service.session.distributedcache.ispn.DistributedCacheManager] Problem accessing session [hz****59+A__]: org.jboss.weld.exceptions.WeldException: WELD-001500 Failed to deserialize proxy object

Note that if you then go to the first address (with port 8080) and then again to 8180 - from now the replication works fine. But IMHO this is not desired behaviour, the second (backup) JBoss instance should be ready immediately

The question is if the changes of the application are the right ones. There is nobody here who could confirm this. Please pay attention to it and comment this issue if it's not correct.
