Ok, my backgrouond builds of 4_6_1_GA_CP05 against EAP 5.0 and JBossAS 5.1.0.CR1 have just finished and both have failed because the logger API is incompatible. The logging API for AS is being tweaked at the moment and Jonathan has been updating TS accordingly. I think this indicates that 4_6_1_GA_CP05 has been built against an unreleased version of JBossAS 5.1 which may still only be in trunk -- in other words don't use it yet. Perhaps Jonathan might know the specifics.
