call another method dicrectly, that all gets compiled into the class file and 
the server does not have any chance to intercept the method call.

Interesting.  I was under the impression that is was implemented via byte code 
instrumentation by the underlying provider in the classloader, in the case of 
JBossAS, jboss-aop.  Thus, there should be no real technical restrictions on 
when the method can be intercepted.  The spec may have additional restrictions 
though.

Is this bean reference restriction stuff mentioned in the spec?  I didn't see 
anything like this under the Interceptors section.

Thanks for the reply.
