        Checks if the given method is a getter method according to Groovy rules. If yes, the corresponding property name is returned. Otherwise, null is returned. This method differs from Groovy 1.6.8 in that the latter doesn't support the "is" prefix for static boolean properties; however, that seems more like a bug.

        Tells whether the specified method is declared (in byte code) in the specified target class or one of its superclasses.
