Spring 3.1.RC1 and PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE

I have the following code snippet.

Code:

---

@Controller
@RequestMapping("/browse")
public class MediaBrowser {
  ...

    @RequestMapping("/**")
    public final ModelAndView listContents(final HttpServletRequest request) {

        String folder = (String) request.getAttribute(
                HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
                ...
    }

---

I access the following url:

http://localhost:8080/myapp/browse

In spring 3.0.6.RELEASE, I got the folder variable as null.
In spring 3.1.RC1, the folder variable is /browse.

Is this a bug or has something changed in spring-3.1?

Thanks for clarifying.

Cheers,
Raghuram
