Google Cloud Connection Server and smack

Question

I'm trying to get a java server set up for communicating to Google's Cloud Connection Server using the smack library. I have set up an app ID and API key through Google APIs and am trying to use the following code:

import javax.net.ssl.SSLSocketFactory;
import org.jivesoftware.smack.Connection;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.PacketListener;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Packet;

public class CloudMessager {

public CloudMessager(){
    ConnectionConfiguration config = new ConnectionConfiguration("gcm.googleapis.com", 5235);
    SASLAuthentication.supportSASLMechanism("PLAIN", 0);
    config.setSASLAuthenticationEnabled(true);
    config.setSocketFactory(SSLSocketFactory.getDefault());

    Connection connection = new XMPPConnection(config);
    // Connect to the server
    try {
        connection.connect();

        connection.login("SENDERID@gcm.googleapis.com", "APIKEY");

        PacketListener myListener = new PacketListener() {
            public void processPacket(Packet packet) {

            }
        };

        // Register the listener.
        connection.addPacketListener(myListener,null);

    } catch (XMPPException e) {
        e.printStackTrace();
    }       
}
}

Which gives me the following error:

SASL authentication PLAIN failed: text: 
at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:342)
at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:221)
at org.jivesoftware.smack.Connection.login(Connection.java:366)
at org.umptyfratz.strongbox.CloudMessager.<init>(CloudMessager.java:25)

I'm at a bit of a loss to figure out where to go from here. Has anyone else successfully connected to CCS using the Java smack library?

Benny- Not yet. I'm going to try to find a proper Google contact to see if they can tell me what's going on. — gunglefunk, Jul 11 '13 at 15:30
Did you come any further - I have exact the same message. BTW: Are you sure that the username is SENDERID@gcm.googleapis.com and not just SENDERID? — Mike Mitterer, Jul 31 '13 at 15:22
Sorry for the confusion - SENDERID@gcm.googleapis.com is definitive right. — Mike Mitterer, Aug 01 '13 at 06:42

Try to debug the connection with this option:

config.setDebuggerEnabled(true);

This'll open a new window with the data sent and received.

If you find something like "Project SENDERID not whitelisted." you have to register your project here.

(This is in the documentation's note too! http://developer.android.com/google/gcm/ccs.html )
