[jboss-user] [JBossCache] - ClassCastException during cache replication

[mraccola]

I am using Hibernate 3.2 ga with JBoss TreeCache 1.3.0.SP2.  The application is clustered and I have setup the cache for REPL_SYNC.  I am now getting the following stack trace on the target machine when the cache replications occur.  This only seems to occur when I enable HTTP session replication on the web container I am using.  (The HTTP session replication is a separate process from the JBoss/JGroups replication.)  Any ideas?
