Unable to receive WNS notification if push with Notification-Hubs-java-sdk-1.0.3.jar

Question

Hi,

I'm trying to push WNS notification with Notification-Hubs-java-sdk-1.0.3.jar, but it doesn't work.
Is there any ways to resolve it? Thanks.

According the descriptions above, I created
an UWP app for receiving WNS notification and a JAVA console for pushing WNS notification.

When I use Notification-Hubs-java-sdk-1.0.3.jar,
hub.sendNotification() returned sucessfully, but the UWP app didn't receive it.
TrackingId: 86726822-6575-4594-a572-d782d698600c

When I use Notification-Hubs-java-sdk-0.4.2.jar,
hub.sendNotification() returned sucessfully, and the UWP app received it.
TrackingId: 240008fe-3beb-4a63-855e-3096735c9032

I checked Metrics Chart on https://portal.azure.com/, Incoming Messages (Sum) increased both 1.0.3 and 0.4.2.
So I think Notification-Hubs got the WNS notification of 1.0.3.

This is the code of JAVA console:

import com.windowsazure.messaging.*;

public class WNSSender {
  public static void main(String args[]) {
    System.out.println("WNSSender Start");
    
    try {
        String connectionString = "Endpoint=sb://...";
        String hubPath = "...";
        NotificationHub hub = new NotificationHub(connectionString, hubPath);

        String toast = "<toast><visual><binding template=\"ToastText01\"><text id=\"1\">Hello from Java Test!</text></binding></visual></toast>";
        System.out.println(toast);
        Notification n = Notification.createWindowsNotification(toast);
        NotificationOutcome outcome = hub.sendNotification(n);
        System.out.println("WNSSender End " + outcome.getNotificationId() + " " + outcome.getTrackingId());
    } catch (Exception e) {
        e.printStackTrace();
    }
  }
}
