passing an array of integers as a paramter to controller

[novax00]

Hello. I have big project on spring 3.0.2 and want upgrade to spring 3.1.3. But there is little problem.

@Controller
public class IndexController{
    @RequestMapping("index7")
    public ModelAndView index7(@RequestParam(value="arr", required=true) Integer[] arr){
        return new ModelAndView("index", "test", "arr="+Arrays.asList(arr));
    }
}

In spring 3.0.2 calling http://localhost:8080/pp/index7.htm?arr= gives arr=[null]. In spring 3.1.3 arr=[].
Calling http://localhost:8080/pp/index7.htm?arr=&arr= and more arguments gives identically [null, null] in both versions
Is it possible to configure spring 3.1.3 like 3.0.2 for this situation? or some binders? or something else?

        return pjp.proceed(args);
    }
