[Bug swing/23900] JFrame doesn't recognize changes in it's ContentPane

The testcase below shows the same bug and shows that calling setSize on the
JFrame causes the JFrame to be properly updated and laid out (provided at least
one of the dimensions increases due to the setSize call).

Testcase: at first everything shows up.  On the JDK typing a line in the console
hides the button, and then another line brings it back up.  Ours never goes away
(although it does have visible == false).

***TESTCASE***
import java.io.*;
import javax.swing.*;
public class Test
{

  public static void main(String[] args) throws IOException
  {
    JFrame jf = new JFrame("title1");
    BufferedReader console = new BufferedReader(new 
InputStreamReader(System.in));
    jf.setSize(600,600);
    jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JButton b = new JButton ("hi");
    jf.setContentPane(b);
    jf.show();
    System.out.println ("but vis: "+b.isVisible());
    console.readLine();
    b.setVisible(false);
    jf.setSize(601,500);
    System.out.println ("but vis: "+b.isVisible());
    console.readLine();
    b.setVisible(true);
    System.out.println ("but vis: "+b.isVisible());
  }
}
