This is a limitation for custom Icons because they will need to use toe
drawImage with appropriate implementation.
To fix that will be a major change and may need change in the implementation of
drawImage method.

If we remove the check, the cases where custom ImageIcon have no images will
fail.
Example:
import java.awt.*;
import javax.swing.*;
public class JInternalFrameBug {
public static void main(String[] args) {
SwingUtilities.invokeLater(
new Runnable() {
public void run() {
try {
UIManager.setLookAndFeel("com.apple.laf.AquaLookAndFeel");
}
catch(Exception e) {
System.out.println("This is not a Mac.");
return;
}
JFrame f = new JFrame();
f.setSize(500, 500);
JDesktopPane dtp = new JDesktopPane();
JInternalFrame jif = new JInternalFrame();
jif.setTitle("Test");
jif.setFrameIcon(
new ImageIcon() {
public int getIconWidth() {
return 16;
}
public int getIconHeight() {
return 16;
}
public void paintIcon(Component c, Graphics g, int
x, int y) {
g.setColor(java.awt.Color.green);
g.fillRect(x, y, 16, 16);
}
});
jif.setSize(400, 400);
jif.setVisible(true);
dtp.add(jif);
f.getContentPane().setLayout(new BorderLayout());
f.getContentPane().add(dtp, "Center");
f.setVisible(true);
}
});
}
}
