Access restriction: The type ‘Application’ is not API (restriction on required library rt.jar)

by

Here is the code:

package mscontroller;

import javax.swing.*;
import com.apple.eawt.Application;

public class Main {
    public static void main(String[] args)
    {
        Application app = new Application();
        app.setEnabledAboutMenu(true);

        AMEListener listener = new AMEListener();
        app.addApplicationListener(listener);
        JFrame mainFrame = new JFrame("Application Menu Example");
        mainFrame.setSize(500, 500);
        mainFrame.setVisible(true);
    }
}

here is the error:

eclipse says this:

Access restriction: The type ‘Application’ is not API (restriction on required library ‘/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/rt.jar’)
