That means we'll need both component-level and per-method lists.  I  
don't see
the benefit of this approach.   Why not just register a single CDI  
impl interceptor
that knows about all the CDI-specific application interceptors?    The  
ejb container
will register it in the right place in the chain and it can delegate  
all the
@PostConstruct , @AroundInvoke, etc. methods appropriately.   If the  
interceptor instance
itself needs some context we can agree on a constructor argument such as
EjbDescriptor.
