Why can't global exception handling handle exceptions thrown in the filter?

My code is looking like this at the moment:

  1. Filter method

     @Override
 public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
     HttpServletRequest   httpServletRequest = (HttpServletRequest) servletRequest;
     String token = httpServletRequest.getHeader("token");
     if (token==null)
         throw new NoTokenException();

     try {
         String s = jwtToken.parseJwt(token);
         httpServletRequest.setAttribute("id",s);
     }catch (Exception e){
         throw new RuntimeException();
     }

     filterChain.doFilter(servletRequest,servletResponse);
 }

  2. Controller advice class

     @RestControllerAdvice
 public class GlobalExceptionHandle {

     @ExceptionHandler(Exception.class)
     public void Handle(Exception e, HttpServletResponse response) throws IOException {
         response.setContentType("application/json;charset=UTF-8");
         response.getWriter().write("msg");
         response.flushBuffer();
     }
 }

@RestControllerAdvice does not work for filters. For them, you need to implement an additional filter as depicted in https://stackoverflow.com/a/34633687/16572295.
