Spring WebArgumentResolver not resolving?

Question

I'm using custom argument resolvers with spring 3.2.4 and everything works fine until now. every now and then I notice that one of my servers is not resolving arguments properly and I was wondering, is there anything I'm doing wrong in the configuration.

Couple of things to mentions - I something use several custom arguments in a method e.g

@RequestMapping(value = "/edit", method = RequestMethod.GET)
public String editMode(@LoggedInUser User user, @UserCompany Company company) throws IOException

and the arguments that are not being resolved are always not the first argument..

any chance I'm missing something in terms of ordering? priority to resolvers?

-- EDIT

My argument resolver is

public class MyHRCompanyResolver implements WebArgumentResolver {


@Inject
private CompanyService companyService;


public Object resolveArgument(MethodParameter methodParameter, NativeWebRequest nativeWebRequest) throws Exception {

    MyHRCompany myHRCompany = methodParameter.getParameterAnnotation(MyHRCompany.class);

    if (myHRCompany == null){
        return UNRESOLVED;
    }

    try {

        Company company = companyService.userCompany(getUser());
        if (company == null)
            return UNRESOLVED;

        return company;
    } catch (Exception e) {
        // log some error
        return UNRESOLVED;
    }
  }
}
