Reproduce:
When using the SwingSet app. Put a breakpoint into JInternalFrame.dispose. This will not be called when using the MetalUI.


The method installKeyboardActions in the BasicInternalFrameUI installs the InternalFrameListener. If the MetalInternalFrameUI overrides this
method without calling the inherited method it will not install the InternalFrameLister.

Resolution:
There are multiple ways to fix this problem.
1. Change the MetalInternalFrameUI to.
  protected void installKeyboardActions(){
super.installKeyboardActions();
  }
2. Change the MetalInternalFrameUI to.
  protected void installKeyboardActions(){
    if (internalFrameListener == null)
      createInternalFrameListener();
    // skip (presume this was the reason for the override
    //openMenuKey = KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, KeyEvent.CTRL_MASK);
    frame.addInternalFrameListener(internalFrameListener);
  }
3. Insert the following code into the BasicInternalFrameUI.installUI
    if (internalFrameListener == null)
      createInternalFrameListener();
    frame.addInternalFrameListener(internalFrameListener);
