Using reflection to determine method overloading

A thread on the DWR mailing list about properly detected overloaded methods with covariant types in JDK5 got me curious. So I put together some quick code to determine if one method overloads another. It works for covariant types, but I didn’t add support for generics. I’m not sure how much more [...]
