> It seems to be a problem with forwarding requests in certain cases. I have the following setup:
> * Servlet A forwards the request to Servlet 2 (using RequestDispatcher).
> * Servlet B writes to the response using an output stream (HttpServletResponse.getOutputStream()).
> When this happens I get an IllegalStateException from Jetty that basically saying that the Writer cannot be closed since I have already used an OutputStream.
> The code that I think is wrong (or possibly not robust enough) is in RequestDispatcherImp line 84. 
> {code}
> if (!request.isAsyncStarted())
> {
>   response.flushBuffer();
>   response.getWriter().close();
> }
> {code}
> The line that causes trouble is:
> {code}
> response.getWriter().close();
> {code}
> We should probably check if we can actually close this writer or just ignore the potential exception.
> In my setup I have one servlet that writes to OutputStream using HttpServletResponse.getOutputStream(). Then I have another servlet that forwards the request to the first servlet.
