> Callback not notified when a server crash in the middle of a request
> --------------------------------------------------------------------
>
> Key: HTTPASYNC-21
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-21
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Affects Versions: 4.0-beta1
> Environment: Mac OSX, Java 6
> Reporter: Franck Wolff
> Fix For: 4.0-beta2
>
>
> When a server crash in the middle of a request, the FutureCallback associated
> with the request is never notified. The same issue occurs in blocking mode,
> when waiting for a future.get() answer.
> Here are simple steps to reproduce this issue:
> Client.java:
> ------------------------------------
> package test;
> import java.util.concurrent.Future;
> import org.apache.http.HttpResponse;
> import org.apache.http.client.methods.HttpPost;
> import org.apache.http.concurrent.FutureCallback;
> import org.apache.http.impl.nio.client.DefaultHttpAsyncClient;
> public class Client {
> public static void main(String[] args) throws Exception {
> DefaultHttpAsyncClient httpClient = new
> DefaultHttpAsyncClient();
> httpClient.start();
> HttpPost request = new
> HttpPost("http://localhost:8080/webapp/servlet";);
> request.setHeader("Content-Type", "text/plain");
> final Future<HttpResponse> future = httpClient.execute(request,
> new FutureCallback<HttpResponse>() {
>
> public void completed(HttpResponse response) {
> System.out.println("completed: " + response);
> }
> public void failed(Exception e) {
> e.printStackTrace();
> }
> public void cancelled() {
> System.out.println("cancelled");
> }
> });
>
> System.out.println("get: " + future.get());
>
> httpClient.shutdown();
> }
> }
> ------------------------------------
> Start a server in debug mode, with a breakpoint at the beginning of the
> doPost method of the targeted servlet. Start the client and, when your
> breakpoint is activated, kill the server. The client application will never
> end...
> Maybe I'm missing something but I would have thought that the failed handler
> would be called in this case and that the get() call would throw an
> ExecutionException.
> Thanks.
