Frame triggers componentMoved and componentResized events when it is restored from iconified state. This is reproducible on Windows platforms starting jdk6. This is not reproducible with jdk5.

To reproduce, run the below code. It shows a Frame in iconified state. Restore it and see for 'Resized', 'Moved' messages in command window.

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

public class FrameEventTest {
    public static void main(String[] args) {
        Frame f = new Frame();
        f.setExtendedState(Frame.ICONIFIED);
        f.setSize(200, 200);
        f.addComponentListener(new ComponentAdapter() {
            public void componentMoved(ComponentEvent event) {
                System.out.println("Moved");
            }
            public void componentResized(ComponentEvent event) {
                System.out.println("Resized");
            }
        });
        f.setVisible(true);
    }
}
