retitling checkboxes does not work

(The description field of this report went missing when I first submitted it.)

Compile and run the following program:

--------
import java.applet.*;
import java.awt.*;

public class test extends Applet
{
   public static void main(String args[])
   {
      Frame f = new Frame("Test");
      test t = new test();

      t.init();
      t.start();

      f.resize(100, 100);
      f.add("Center", t);
      f.show();
   }

   public void init()
   {
      setLayout(new BorderLayout());
      add("Center", new Test());
   }
}

class Test extends Panel
{
   Checkbox box = new Checkbox("i am happy");
   
   public Test()
   {
      setLayout(new BorderLayout());
      add("Center", box);
   }

   public boolean action(Event evt, Object obj)
   {
      if (evt.target instanceof Checkbox)
      {
Checkbox box = (Checkbox) evt.target;

if (box.getState())
{
box.setLabel("happy i am");
} else {
box.setLabel("sad = 1");
}
      }
      return true;
   }
}
--------

When the checkbox is pressed, X (probably Motif) complains with:

Warning:
    Name: i am happy
    Class: XmToggleButton
    Invalid XmNlabelString - must be a compound string

The description field as copied from bug report 1234619 follows:


When a checkbox is added to an applet and then its label is changed using setLabel()
it generates a warning (and infact the label remains unchanged).

Here is the result of executing CheckboxTest2.java from the AWT test suite.

[284] [awt] ? appletviewer CheckboxTest2.html
thread applet-CheckboxTest2.class find class CheckboxTest2
Opening stream to: file:/home/vijay/jdk-ws/src/share/test/awt/CheckboxTest2.class to get CheckboxTest2
Warning:
    Name: WrongLabel1
    Class: XmToggleButton
    Invalid XmNlabelString - must be a compound string

Warning:
    Name: WrongLabel1
    Class: XmToggleButton
    Invalid XmNlabelString - must be a compound string
^C

However if the buttons are added to a panel which is then added to the applet,
and then its label is changed, the motif warning doesnt appear and the label change
works fine.
