DerMas, thanks for help.
I'm afraid what I'm looking for is actually not supported. Dynamic interception
won't help 'cause I have to reflect aspectized classes.

I'd like to add mixins to all the classes annotated with:
@Mixins(value={Mixin1.class, Mixin2.class})
public class TargetClass {
}
My understanding is that I have to define 2 aspects for Mixin1 and Mixin2
classes. But I can't work out pointcuts for them. Could anybody help me?
