I think that the easiest way to address this would be to allow the
interceptor to inject the Bean and AnnotatedType object for the intercepted
object.
e.g.
@Inject @InterceptedMetadata Bean bean;
@Inject @InterceptedMetadata AnnotatedType type;
In theory the AnnotatedType could be null, but in practice custom beans
don't support interceptors, so this should be fine.
This allows the interceptor to read the annotation information from the
AnnotatedType. We could also allow beans to inject this information as well,
but I think that this can be implemented as a portable extension without any
spec changes.
The approach taken by decorators immediately comes to mind. I think the
availability of this information would really revolutionize the Java EE
approach to interception. I know if I showed this in a presentation I would
get some raised brows ;)
