Any solution for Class.getMethod() reflection and autoboxing?

Question

I want to use

Class.getMethod(String name, Class... parameterTypes)

to find the method I need to invoke with the given parameters, but apparent

Answer 1

Yeah you need to use Integer.TYPE or (equivalently) int.class.

Update: "My parameterTypes array comes from somewhere and I know that it will only return non primitive types." Well, then that's this "somewhere"'s problem. If they don't give you the proper signature of the method they want, then how are you going to find it? What if there are two overloaded methods, that differ only in one of them takes a primitive and the other one takes the wrapper class? Which one does it choose then? I mean, if you really have no choice then I guess you could just loop through all the methods, and look for one with the right name, and manually check all the parameter types for whether they are correct, or are the primitive equivalents.
