I don't believe that's the case. The current implementation of MultipartRequestWrapper uses exactly the same technique that Ramiro mentions to allow compilation against the Servlets 2.3 API. Adding extra methods to the implementation class allows it to compile against the newer API, while the methods become just ordinary class methods when compiled against the older API.
It's true that the dummy methods added to satisfy the newer API are not useful (without the use of reflection, as you suggest below), but that doesn't seem to have caused problems for people using the Servlets 2.3 API while we've been dummying up the methods new to that version over Servlets 2.2.
Well, I ran into this the other day -- and while it seemed like I could just no-op (or wrapper) for the new methods in the Servlet API (getLocalAddr() etc.) there are other problems in the taglibs against the JSP API -- because JSP 2.0 introduces new classes like ExpressionEvaluator.
