-----------------------------------------------------------

Two AliasToBeanResultTransformer objects should only be equal and have the same hash code if their resultClass is equal. Getters/setters are determined by aliases, which are provided as an argument, so they are not needed to determine equality.

      was (Author: gbadner):
    Two AliasToBeanResultTransformer objects should only be equal and have the same hash code if they have the same getters/setters; otherwise, cache hits could return data intended for different getters/setters.
