Hi,
I am trying to use Jetty 9.4.7 + JDK1.8.0_141 as the HTTP2 client. During
trying to set up the connection to the HTTP2 server, it seems that the
handshake process is successful, however, the HTTP2 client session failed to be
retrieved with idle_timeout. Below is the Jetty log. Could you please do me a
favor to have a check on the coding or settings for this try?

2. Coding
Actually I used the jetty sample client code. The difference is that I put it
to an eclipse project with ant build, and to build a war package for the
deployment.
In below code, after "session = sessionPromise.get(5, TimeUnit.SECONDS);" is
executed, my test result shows that "The retrieved session is null" is printed.
So the client session failed to be retrieved.
//------------------------------------------------------------------------------------------------------------------------
// Fetch/Create and start HTTP2Client.
FuturePromise<Session> sessionPromise = new FuturePromise<>();
HTTP2Client client = null;
// createHttp2Connection(host, port);
PLogger.warn("Creating Http2 connection to " + host + ":" +
port);
ALPN.debug = true;
SslContextFactory sslContextFactory = new
SslContextFactory(true);
// sslContextFactory.addExcludeCipherSuites("TLS_DHE_RSA.*");
client = new HTTP2Client();
client.addBean(sslContextFactory);
try {
client.start();
} catch (Exception e2) {
e2.printStackTrace();
}
client.connect(sslContextFactory,
new InetSocketAddress(host, port),
new
ServerSessionListener.Adapter(), sessionPromise);
long connTime = System.currentTimeMillis();
PLogger.warn("Connected to " + host + ":" + port + " in ms" +
(connTime - startTime));
// Obtain the client Session object.
Session session = null;
try {
session = sessionPromise.get(5, TimeUnit.SECONDS);
} catch (InterruptedException | ExecutionException |
TimeoutException e1) {
e1.printStackTrace();
}
if (null == session) {
PLogger.warn("The retrieved session is null");
} else {
PLogger.warn("Successfully retrieved session");
}
long sessionTime = System.currentTimeMillis();
PLogger.warn("POST session in ms" + (sessionTime - connTime)
+ " to " + host + ":" + port);
// Prepare the HTTP request headers.
HttpFields requestFields = new HttpFields();
requestFields.put("User-Agent", client.getClass().getName() +
"/" + Jetty.VERSION);
requestFields.put("Content-Type", "application/xml");
// Prepare the HTTP request object.
MetaData.Request request = new MetaData.Request( "POST",
new HttpURI("https://"; + host + ":" + port +
"/ParlayREST/callnotification/v1/subscriptions/callEvent"),
HttpVersion.HTTP_2, requestFields);
// Create the HTTP/2 HEADERS frame representing the HTTP
request.
HeadersFrame headersFrame = new HeadersFrame(request, null,
false);
CountDownLatch latch = new CountDownLatch(1);
// Prepare the listener to receive the HTTP response frames.
Stream.Listener responseListener = new
Stream.Listener.Adapter() {
@Override
public void onHeaders(Stream stream, HeadersFrame
frame) {
int duration1 = (int)
TimeUnit.NANOSECONDS.toSeconds(System.currentTimeMillis() - sessionTime);
if (frame.isEndStream())
latch.countDown();
PLogger.warn("After ms" + duration1 + " get
headers");
}
@Override
public void onData(Stream stream, DataFrame frame,
Callback callback) {
byte[] bytes = new
byte[frame.getData().remaining()];
frame.getData().get(bytes);
int duration = (int)
TimeUnit.NANOSECONDS.toSeconds(System.currentTimeMillis() - sessionTime);
PLogger.warn("After ms" + duration + " get "
+ new String(bytes));
callback.succeeded();
if (frame.isEndStream())
latch.countDown();
}
};
// Send the HEADERS frame to create a stream.
FuturePromise<Stream> streamPromise = new
FuturePromise<Stream>();
if (null == session) {
PLogger.warn("The session is null");
return;
}
session.newStream(headersFrame, streamPromise,
responseListener);
