      Description

      GridBagLayout adds any component handed to it via the addLayoutComponent
      method to an internal hashtable. It does nothing upon the invocation of
      removeLayoutComponent.

      Thus,

      JFrame frame = new JFrame("Test");
      frame.getContentPane().setLayout(new GridBagLayout());
      frame.getContentPane().add(componentA);
      frame.getContentPane().add(componentB);
      frame.getContentPane().add(componentC);
      frame.getContentPane().remove(componentA);
      frame.getContentPane().remove(componentB);
      frame.getContentPane().remove(componentC);

      // At the end, the container content pane no longer has any references
      // to the components, but there are references to the three components
      // in the comptable hashtable in the GridBagLayout component
