[Bug swing/23920] setting the layeredPane in a RootPaneContainer causes weird behaviour

This behaviour is caused because our LayeredPane has a layoutManager attached
and this layoutManager's layoutContainer method is called after
RootLayout.layoutContainer (properly) sets all the sizes.  The testcase below
shows 2 problems, the first being that our LayeredPane has a layoutManager
attached while the JDK does not, and the second that our GlassPane uses a
BorderLayout layoutManager while the JDK uses FlowLayout for this.

import javax.swing.*;
import java.awt.Container;
public class TestCase
{
  public static void main(String[] args)
  {
    JFrame jf = new JFrame();

    JLayeredPane jl = new JLayeredPane();
    jf.setLayeredPane (jl);
    jf.setSize(600,600);
    JInternalFrame frame = new JInternalFrame("title2", true, true, true, true);
    frame.setSize(100,100);
    jf.setContentPane(frame);
    frame.show();
    jf.show();

    if (jl.getLayout() == null)
      System.out.println ("LAYERED PANE LAYOUT IS NULL");
    else 
      System.out.println ("Layered pane layout:
"+jl.getLayout().getClass().getName());

    System.out.println ("glass pane layout:
"+((Container)jf.getGlassPane()).getLayout().getClass().getName());
  }
}
