I ran into a version conflict on jboss-ejb3-ext-api-impl (/ jboss-ejb3-impl). AS 5.0.0.Beta4 uses 0.1.2.Beta1. These do not contain implementation for interceptor annotations. So I upgraded to 0.1.3-SNAPSHOT. This one however contains a conflicting ClusteredImpl. Normally this would mean a backport of interceptor implementations to another minor (in this case we can only go for 0.1.2.Beta2). But it turns out that a better option is removing the dependency of ejb3-ext-api-impl in ejb3-interceptors. So this means that ejb3-ext-api-impl should slowly empty out into the different components and then be trashed.
