Lookup.findSpecial fails on Object method call from an interface because of a bug in the implementation calling `Class::getSuperclass` on an interface which has no superclass. The implementation should only search the method from its superclass only if it's a class. This patch is trivial and skip the superclass search if it's an interface.
