java version "1.2.2"
HotSpot VM (1.0.1, mixed mode, build g)

Compile the following test program and run it via the 1.2.2 applet viewer under
NT (with active desktop update). Load the web page which references the applet
from a web server rather than as a file.

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

public class test extends JApplet
{
    public void init()
    {
        JFrame jf = new JFrame( "test" );
        Container jc = jf.getContentPane();
        jc.setLayout( new BorderLayout() );
        jc.add( new JLabel( "ABCDEFGHIJKLMNOPQRSTUVWXYZ" )
                BorderLayout.CENTER );
        jf.pack();
        jf.show();
    }
}

If I minimize the JFrame then restore it, the text disappears. Depending on how
I size and position the JFrame before minimizing it, the text can appear in the
wrong place.
If my policy allows display of applet windows without a warning banner, the
JFrame is well behaved: it looks just the same after being restored.

Classic VM (build JDK-1.2.2-W, native threads, symcjit)

Problem: An applet launched JFrame does not redraw correctly
upon being restored from a minimized state. To reproduce the
problem compile and run the following java source (Test.java):

// Test.java

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

public class Test extends JApplet {

    public void init() {
        AFrame frame = new AFrame();
    }

    class AFrame extends JFrame {

        public AFrame() {
            JButton button = new JButton("test");
            getContentPane().add(button);
            setSize(100, 100);
            setVisible(true);
        }

    }

}

// eof Test.java

Use the following HTML code to run the applet:

<title>Test</title>
<applet code="Test.class" width=350 height=100>
</applet>

Run the applet with appletviewer:

  appletviewer test.html <CR>

When the JFrame pops up with the JButton on it, minimize the
frame and then restore it -- the JButton will be skewed.

/* This program basically pops up a JFrame with a JPanel inside of it.
 *
 * If you then iconify the frame and deiconify it subsequently,
 * it is not laid out properly. You have to resize it before it
 * is shown properly.
 *
 * The workaround seems to be to invalidate() the container jframe on
 * window deiconify event. (This seems to indicate that the container
 * is not getting invalid when it is iconified and hence it is not
 * being laid out when de-iconified?)
 *
 * Env:
 * Java(TM) Plug-in: Version 1.2.2.p005
 * OR Appletviewer that is part of JDK1.2.2
 * WinNT 4.0 with service pack 5
 * netscape 4.73 or IE 5.00.2314.1003

This bug is reproducible only on win_nt. To reproduce
move the JFrame window before iconifyingit.
Not reproducible on Solaris.
