Java/OS X Lion: Setting application name stopped working with JDK1.7

I hitherto used the following code to set the Application Name (in the top "System" menu bar) on my Apple MacBook. (Actually, I think I copied this from stackoverflow.)

Basically, have a seperate AppLauncher class that uses System.setProperty() to set the application name before creating a new Runnable for the app itself.

Worked just fine.

However, since I downloaded and started using JDK 1.7, the solution stopped working - I'm getting the Class Name instead of the App Name in the menu, just like before I found that solution. I tried googling it, but to no avail.

Here is the defunct code that used to work under JDK 1.6, reduced to the relevant parts:

public class AppLauncher {
public static void main(String[] args) {

    System.setProperty("apple.laf.useScreenMenuBar", "true");
    System.setProperty("com.apple.mrj.application.apple.menu.about.name",
                "My Application");
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

    javax.swing.SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            new MainWindow();
        }
    });
}
}

Thanks for suggestions!

ETA: invoking with java -Dapple.laf.useScreenMenuBar=true still works. Pu8tting the property into Info.plist might work, but I haven't tried it yet.
