Re: [aspectj-users] Beginner question: intercepting method within a cer

[Mohan Radhakrishnan <radhakrishnan.mohan@xxxxxxxxx>]

Hi,
       Don't mean to divert the OP but I just tried this using 1.6.9
and I am not using the annotation style and

        pointcut p1() : call(* *.invoke(..)) && !within( is(AnonymousType) );

does not match and

        pointcut p1() : call(* *.invoke(..)) && within( is(AnonymousType) );

matches.

Looks like 'AnonymousType' is working as intended ?

Thanks,
Mohan
