bug in sample code at https://hc.apache.org/httpcomponents-asyncclient-4.1.x/quickstart.html

[Ron Reynolds]

httpclient.execute(producer3, consumer3, new FutureCallback<HttpResponse>()
{
        public void completed(final HttpResponse response3) {
            latch2.countDown();
            System.out.println(request2.getRequestLine() + "->" +
response3.getStatusLine());
        }
        public void failed(final Exception ex) {
            latch2.countDown();
            System.out.println(request2.getRequestLine() + "->" + ex);
        }
        public void cancelled() {
            latch2.countDown();
            System.out.println(request2.getRequestLine() + " cancelled");
        }
    });

i believe all the "request2"s should be "request3"s.

wasn't sure if there was a better list to send this errata to...
