Keith Naas commented on JBSEAM-332:
-----------------------------------

It appears to be a problem with ANY CGLIB Enhanced class being putinto the session.  We have a test case with just an Enhanced Foo object.  The same error message appears in the server log of the server we are failing over to.

>         Environment: Seam 1.0, JBoss 4.0.4GA, Windows Server 2003, Cluster of 4 nodes on 2 machines.

> We have an application that makes use of JavaBeans for a lot of our JSF "actions".  When one of our nodes is brought down, the session should Seamlessly failover to another node.  The user is sent  to a different node, but the entire session appears to be in a clean state.   We looked through the server logs and saw the following:

> All of our beans are Serializable, but it appears that there is an issue with the cache sync of the CGLib proxy classes.  This specific bean does have some service properties that are transients.  It also has properties that refer to other Web JavaBeans.  
> We will be investigating this some more, but we wanted to get this logged since it appears to be a major issue that prevents us from clustering our Seam apps.
