HttpServletResponse won't stream bytes to client

Question

I've been trying to figure out why the Servlet won't return the bytes to the client with this code (although the bytes is read based on the logs):

Redirector redirector = new SelfInjectingRedirector(getContext(), targetPattern,
        Redirector.MODE_SERVER_OUTBOUND){

    @Inject
    FileStore fileStore;

    String fileName = "something_for_sample";
    boolean isBufferFirst = true;

    @Override
    public void handle(Request request, Response response) {
        try {
            HttpServletRequest servletRequest = ServletUtils.getRequest(request);
            HttpServletResponse servletResponse = ServletUtils.getResponse(response);
            //
            // Either statement here wont return the bytes to the client
            // 
            if(isBufferFirst) {
                byte[] bytes = fileStore.get(fileName);
                System.out.println("Bytes read: " + bytes.length); // Bytes read: 5731
                servletResponse.getOutputStream().write(bytes, 0, bytes.length)
            } else {
                fileStore.get(fileName, servletResponse.getOutputStream());
            }
        } catch (Exception e) {
            response.setStatus(Status.SERVER_ERROR_INTERNAL);
            e.printStackTrace();
        }
        System.out.println("Handle Done");
    }

};

Here's the class heirarchy "SelfInjectingRedirector extends Redirector" and "Redirector extends Restlet" as in org.restlet.Restlet — quarks, Jul 22 '17 at 06:38
Since this is not using anything standard it's really impossible to tell. What is "Response"? What is "ServletUtils"? What is FileStore? — stdunbar, Jul 23 '17 at 01:23

The solution is to add the "Content-Length" header.
