PopupMenu.show() is not always throwing IllegalArgumentException
Incorrect exception throwing can be demonstrated on following example:

import java.awt.*;
import java.awt.event.*;


public class PopupMenuShowExceptions
{

    public static void main(String args[]) throws Exception {
        Frame f = new Frame();
        Button b = new Button();
        Label l = new Label();
        PopupMenu pm1 = new PopupMenu();

        f.add(l);
        f.show();
        Robot r = null;
        try {
            r = new Robot();
        } catch (Exception ex) {
            Sysout.println("Error creating robot");
            return;
        }

        r.delay(1000);
        try {
            l.add(pm1);
            pm1.show(b, 0, 0);
            r.delay(1000);
            Sysout.println("Exception is not thrown when showing Popup Menu on component not in parent's hierarchy");
            return;
        } catch (IllegalArgumentException ex) {
            Sysout.println( "Correct exception when showing popup menu on non-created component");
            Sysout.println("Exception: " + ex);
            return;
        } catch (Exception ex) {
            Sysout.println("Incorrect exception thrown: " + ex);
            return;
        }
        Sysout.println();
      
    }//End init()
}
