IMHO a better way that we discussed and rejected, opting for a smaller change, is to create a NonInflatingMethodAccessor and just drop in one of those without a delegate for when creating the accessor for methods/ctors on anonymous classes.
Even better. I would name the new class NativeMethodAccessorImpl and the one doing inflation InflatingNativeMethodAccessorImpl which would extend NativeMethodAccessorImpl, override invoke() and call super.invoke()... This way, no native methods duplication is needed. invoke() is already an interface method with 2 implementations. Now it will have 3. Does this present any difference for dispatch optimization?
