Argument names are stored in the compiled code only when it's compiled in debug mode, so you should either compile it in debug mode or supply @RequestParam with explicit parameter names. The latter approach is more reliable because it doesn't depend on the environment:

@RequestMapping(value = "/security/login", method = RequestMethod.POST) 
public ModelAndView login(@RequestParam("userName") String userName, 
    @RequestParam("password") String password,  
    HttpServletRequest request) {
