java.nio.channels.ClosedChannelException HTTP/2与jetty

我正在尝试使用HTTP/2向生产中的设备发送apple通知

我将这个-Xbootclasspath/p:/home/mohamed/Desktop/alpn-boot-8.1.9.v20160720.jar作为eclipse中的默认VM参数传递

以下是我现在使用的代码：

public static void pushoNotification() {
    try {
        // create a low-level Jetty HTTP/2 client
        HTTP2Client lowLevelClient = new HTTP2Client();
        lowLevelClient.start();

        // APNs requires the use of HPACK (header compression for HTTP/2), which prevents repeated header keys and values.
        KeyStore ks = KeyStore.getInstance("PKCS12");

        // Ensure that the password is the same as the one used later in setKeyStorePassword()
        ks.load(PushNotifications.class.getClassLoader().getResourceAsStream("Prod2.p12"), "a12B34".toCharArray());

        SslContextFactory ssl = new SslContextFactory(true);
        ssl.setKeyStore(ks);
        ssl.setKeyStorePassword("a12B34");

        // create a high-level Jetty client
        HttpClient client = new HttpClient(new HttpClientTransportOverHTTP2(lowLevelClient), ssl);
        client.start();

        // request-response exchange
        ContentResponse response = client.POST("https://api.push.apple.com").path("/3/device/19297dba97212ac6fd16b9cd50f2d86629aed0e49576b2b52ed05086087da802")
                .content(new StringContentProvider("{ \"aps\" : { \"alert\" : \"Hello\" } }")).send();
        response.toString();
        client.stop();
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (ExecutionException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

但是当我从main方法运行这个方法时，它抛出java.nio.channels.ClosedChannelException

我在eclipse控制台中也得到了这个 INFO org.eclipse.jetty.http2.HTTP2Session-通知侦听器org.eclipse.jetty.http2.client.http.HttpClientTransportOverHTTP2时失败$SessionListenerPromise@87eaf9c

有什么想法吗

这是我的配置文件：

APPLE_NOTIFICATION_PRODUCTION_HOSTNAME=api.push.apple.com
APPLE_NOTIFICATION_PORT=2197
APPLE_APNS_TOPIC=MyAPNS_Topic(plz change it)

最后，这里是我在项目中使用的罐子：

APPLE_CERTIFICATE_PATH=/my/apply/certificate/path/so/plz/change/it/Certificates.p12
APPLE_CERTIFICATE_PASSWORD=myPassword(plz change it)
KEYSTORE_TYPE=PKCS12
APPLE_NOTIFICATION_DEVELOPMENT_HOSTNAME=api.development.push.apple.com
APPLE_NOTIFICATION_PRODUCTION_HOSTNAME=api.push.apple.com
APPLE_NOTIFICATION_PORT=2197
APPLE_APNS_TOPIC=MyAPNS_Topic(plz change it)
