Jetty HttpClientTransportOverHTTP2 with SSL

I am trying to make a simple GET request using Jetty's HttpClientTransportOverHTTP2, but it fails. Here is my code:

import org.eclipse.jetty.client.HttpClient;
import org.eclipse.jetty.client.api.ContentResponse;
import org.eclipse.jetty.http2.client.HTTP2Client;
import org.eclipse.jetty.http2.client.http.HttpClientTransportOverHTTP2;
import org.eclipse.jetty.util.ssl.SslContextFactory;

public class JettyClientExample {

    public static void main(String[] args) throws Exception {
        HttpClientTransportOverHTTP2 clientTransport = new HttpClientTransportOverHTTP2(new HTTP2Client());
        HttpClient client = new HttpClient(clientTransport,  new SslContextFactory(true));
        client.start();
        ContentResponse response = client.GET("https://http2.akamai.com");
        System.out.println("Version: " + response.getVersion());
        System.out.println("Status: " + response.getStatus());
        System.out.println("Content: " + response.getContentAsString());
    }
}

And here is the Exception I get in the line client.GET("https://http2.akamai.com")

I am using version 9.3.3.v20150827, and I put the ALPN JAR into my boot classpath with -Xbootclasspath/p:<path>.

For some reason, I didn't find any working example of HttpClientTransportOverHTTP2 with SSL on the Internet.

What am I missing?
