JBoss AOP 2.0.0.CR3 has been released today. Thanks to Jason Greene's help, I have found out that the problem was being caused by an incompatibility with JBoss AOP 2.0.0.Beta1, which requires recompilation of Pojo Cache. Before this recompilation, the JBoss AOP version cannot be upgraded in the AS. Kabir and Jason are coordinatinating our AOP release with a new release of PojoCache for that matter.
