mvc Parameter annotations are not inherited [SPR-14526]

[spring-projects-issues]

Terence Mill opened SPR-14526 and commented

 @RequestMapping(method = RequestMethod.GET, value = "/{userId}", produces = "application/json", consumes = "application/json")
public IUser getUserById(@PathVariable("userId") Long userId);

Calling @Get on PROT://DOMAIN/users/1 -> userId is NULL :(

@RequestMapping("/users") public interface IUserEndpoint {..} 

@RestController public class UserEndpoint extends implements IUserEndpoint {..}

(!) It only works if i repeat @PathVariable in my implementing @RestController

@RestController public class UserEndpoint extends implements IUserEndpoint {
public IUser getUserById(@PathVariable("userId") Long userId);

Repeating the REST contract is an ugly workaround
