The VM native reflection implementation does not know about this alternate `reflected$XXX` mechanism. No VM change in this patch and so we ensure this be called via the generated bytecode for Method::invoke rather than going through the VM native reflection which reduces startup overhead.

As this case is forced not to go through VM reflection support, unless I miss something, DelegatingMethodAccessorImpl/NativeMethodAccessorImpl has no need to be changed. I will double check with the VM runtime team.
