Find a method. Attempts to find the most specific applicable method using the algorithm described in the JLS section 15.12.2 (with the exception that it can't distinguish a primitive type argument from an object type argument, since in reflection primitive type arguments are represented by their object counterparts, so for an argument of type (say) java.lang.Integer, it will not be able to decide between a method that takes int and a method that takes java.lang.Integer as a parameter.
This turns out to be a relatively rare case where this is needed - however, functionality like this is needed.
