Continuously pressing Ctrl+F4 (or a Look and Feel specific shortcut for closing a frame) in a JDesktopPane causes an
ArrayIndexOutOfBoundsException.

Closing the last/only JInternalFrame in a JDesktopPane
using the keyboard shortcut Ctrl+F4 causes an
ArrayIndexOutOfBoundsException. Apparently the UI
tries to select the next internal frame when there
is none. The problem doesn't appear when the mouse
is used to close the internal frame (by clicking
on the X icon).

===

Test case:

import java.awt.*;
import javax.swing.*;

public class JIFCloseTest extends JFrame {
  public JIFCloseTest() {
    super("JIFCloseTest");
    
    JDesktopPane dsktpPn = new JDesktopPane();
    
      JInternalFrame intFrm = new JInternalFrame("JInternalFrame");
      intFrm.setClosable(true);
      intFrm.setBounds(new Rectangle(16, 16, 300, 200));
      dsktpPn.add(intFrm);
      
    setContentPane(dsktpPn);
    
    setSize(new Dimension(608, 384));
    setLocation((getToolkit().getScreenSize().width - getWidth()) / 2,
      ((getToolkit().getScreenSize().height) - getHeight()) / 2);
      
    show();
    
    intFrm.setVisible(true);
  }
  
  public static void main(String[] args) {
    new JIFCloseTest();
  }
}
