Yes

Not sure I understand the question. I've just worked with what was provided, but we need some tests testing the scenario I outlined. We would need to check the Signature attribute of the method and then construct the parameterized ClassInfo as was done for getGenericSuperClass().

The main thing is knowing the index of the type parameter we are looking for in the parent class, then getting the type argument using that index used when extending that class and matching that up with the type parameters of the child class. This needs doing for the whole hierarchy. This has been done, but needs some better tests

I'll try that
