[jboss-as7-dev] EJB passivation/activation, clustering and JPA extended persistence context handling...

[Brian Stansberry]

Throwing NotSerializableException instead of serializing means removing 
support for clustering SFSBs with an XPC. That IMHO would be a pretty 
major feature regression. I believe we have supported that since AS 4.2 
if not earlier.
