Following construct doesn't work in a Controller. Superclass: @RequestMapping(params = "action=edit", method = RequestMethod.GET) public String delete(@RequestParam("id") ID id) {...} Subclass: @Override public String delete(@RequestParam("id") Integer id) {...} ID extends Serialiazable. The HandlerMethodResolver resolved the method Subclass.delete(Serializable). This is incorrect: it should get the bridged method Subclass.delete(Integer), so it can resolve the @RequestParam annotations. I think this wil be fixed if BridgeMethodResolver.findBridgedMethod(method) is called after using ClassUtils.getMostSpecificMethod().
