SlingFilter не ловит исключения?

Я реализую фильтр аутентификации, а также использую его для обработки исключений. Так как в CQ5 нет файла web.xml, мы не можем поставить такое сопоставление, как <exception-type>.

Все мои контроллеры (сервлеты) возвращают Exception вызывающему абоненту. И у меня есть фильтр, который вызывается перед каждым из моих сервлетов. Поэтому я явно бросаю

new SerlvetException()  

в одном из моих сервлетов. Это, конечно, передается вызывающей стороне, то есть моему основному фильтру. Исключение происходит правильно в chain.doFilter(), и я обрабатываю исключение здесь (в фильтре). но это просто не обрабатывается, почему? Кроме того, что это за свойство Scope SlingFilter? Я не понимаю это свойство REQUEST, ERROR, COMPONENT, INCLUDE SlingFilter SCOPE

Вот мой код и трассировка стека.

public class AddNewUserController extends SlingAllMethodsServlet{

    /**
     * @author Oliver Kaunds
     */

    private static final long serialVersionUID = 1L;

    private final Logger log = LoggerFactory.getLogger(this.getClass());



    @Reference
    protected AddNewUserService addNewUserService;

    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException
    {


        log.info("VideoJet :: Do GET Called ");
        String path =request.getRequestURI();
        log.info("VIDEOJET PATH :: "+ path);
        try{
            if(path.equals("/services/videojet/v1/AddNewUserController/view"))
            {


                List<HRRepresentative> list =addNewUserService.getHRRepresentative();
                request.setAttribute("hrList",list );
                HttpSession session = request.getSession();
                String userOperation =(String)session.getAttribute("userOp");
                request.setAttribute("userOp", userOperation);
                session.removeAttribute("userOp");
                throw new Exception("Error Page Test"); // Manuly throw exception

            }

И мой главный фильтр

        }



    }

    public void init(FilterConfig config) throws ServletException {

    }

}

Исключение происходит правильно, но не перехватывается блоком catch. трассировка стека ниже.
