Bruno, I'm working on reproducing it, it did not happen during any of our testing. I'm working on modifying our scripts so that we can reproduce it locally.
My gut is that it's related to deserializng a replicated value in the session. I'm thinking of disabling clustering in tomcat and restarting our app, (without session replication). Just so we have the other node running.
