             Summary: The client dose not check if the IO thread is alive
                 Key: HTTPASYNC-119
                 URL: https://issues.apache.org/jira/browse/HTTPASYNC-119
             Project: HttpComponents HttpAsyncClient
          Issue Type: Bug
         Environment: Mac OSX, Java 8
            Reporter: wang qi


When I developed with HttpAsyncclient, it was hard for me to know whether the IO thread in BaseIOReactor was alive。 For example, if I throw an error in the callback，the IO thread will terminate,but the connecting thread  will not check if the IO thread is alive,and will still add new  channels to the dispatcher。

The java code:

 CloseableHttpAsyncClient client = HttpAsyncClients.custom().build();
        client.start();
        HttpUriRequest getRequest = new HttpGet("www.google.com");
        client.execute(getRequest, new FutureCallback<HttpResponse>() {
            @Override
            public void completed(HttpResponse result) {
                throw new StackOverflowError();
            }

            @Override
            public void failed(Exception ex) {

            }

            @Override
            public void cancelled() {

            }
        });
        for(int i = 0 ; i < 100 ; i++){
            client.execute(getRequest, new FutureCallback<HttpResponse>() {
                @Override
                public void completed(HttpResponse result) {
                    
                }

                @Override
                public void failed(Exception ex) {

                }

                @Override
                public void cancelled() {

                }
            });
        }

one of the IO threads is dead，but the java Error dose not be caught，and hte client will continue work and add new channels to the dispather, but the newChannel queue will be not be consumed, so I want to know is there any method to deal with this situation.
Thanks
