Consider mechanisms to support "transient" session attributes, i.e. attributes that don't replicate.

A couple concepts:

1) A general jboss-web.xml flag. If set, tests any attribute for serializability before replicating; if not serializable don't include it in the serialized form.

2) A jboss-web.xml block where specific attribute names could be listed for exclusion.

Marking this JIRA as "No Release" as I'm adding it to record an idea that came up as a tangent in a support case discussion. Not on any short-term roadmap unless someone in the community expresses interest in exploring the idea and implementing it. "Exploring it" in the sense of validating any use cases to see if they make sense.
