Andrew Dinn is reporting some problems with javassist 3.11 (see http://lists.jboss.org/pipermail/jboss-development/2010-January/015624.html) and Kabir indicates that AS shouldn't need to move beyond 3.10. So, look at reverting back.

I'll do this the first week of Feb after the smoke is cleared from the component upgrades coming in right now for the M2 cutoff.
