Hmm, since both annotation and method signature attributes' recorded signature/annotations don't exactly correspond to the parameters in the descriptor, I thought they probably would share the same mechanism of determining the exact parameter mapping. Reflection uses `MethodParameters` attribute's modifiers to determine how signatures apply to parameters, while it handles annotation in a separate way.

This indeed doesn't matter as the extra local variables passed are in the end of parameter list, which doesn't impact the current way annotations are written to class files and read at runtime. Sorry for digressing here.
