you do not want exposed as a mix-in, simply pass the interface to the
suppressInterface() method of the DelegatingIntroductionInterceptor class.
Now we said that you do not have to implement invoke(), but you can if your
Any ideas, resources,sample code,links, highly appreciated. thanks in advance.
