Summary:
Use $interface_name instead of $class_name when dealing with
interfaces. Problem happens when you extend an interface:
interface SubIface extends SuperIface { ...
Notice: Undefined variable: class_name in ...
Fatal error: Call to a member function getConcreteString() on a
non-object in ...
Test Plan: phutil_mapper.php works!
