I think that will require a new seam release due to the update of hibernate in the 5.x trunk. Also even when I built the 5.x trunk on the svn revision before the hibernate upgrade and we still had a redeployment issue due to the persistence.xml being not being filtered out in ear. Pmuir and one other guy on irc got me to that point but they said that even with the new deployers some other jars needed to be updated. I would be happy to test if you think this is working now but the trunk wasn't working with seam 2.2.0 a couple weeks ago.
