I have some code at the end of this reply that exhibits this behavior. I'll
file a bug on apple's bugreporter. It just seems odd that such simple stuff
would be so weird. I feel like I'm missing something fundamental here.

Thanks for the tip. It turns out that the Jazzy project has something
useable (although not with realtime spellchecking).

Begin code:

import java.awt.*;
import java.lang.reflect.Method;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import com.apple.mrj.*;

public class SpellTest extends JFrame
{

private JTextArea one,two;
private Object spellOne, spellTwo;
private boolean realTimeChecking = false;

public SpellTest() {
try {
one = new JTextArea(10,40);
two = new JTextArea(10,40);
Class driverClass =
java.lang.Class.forName("com.apple.spell.ui.JTextComponentDriver");
spellOne = driverClass.newInstance();
spellTwo = driverClass.newInstance();
JButton toggleButton = new JButton("Toggle Realtime");
toggleButton.addActionListener(new ActionListener() {
public void
actionPerformed(ActionEvent ae) {
toggleRealtimeSpellcheck();
}
});
JPanel jp = new JPanel();
one.setBorder(BorderFactory.createLineBorder(Color.black));
two.setBorder(BorderFactory.createLineBorder(Color.red));
jp.add(one);
jp.add(two);
jp.add(toggleButton);
setContentPane(jp);
pack();
setVisible(true);
toggleRealtimeSpellcheck();
} catch (Throwable t) {
t.printStackTrace();
}
}


public void
setRealtimeSpellcheck(boolean c) {
if (c) {
System.err.println("turning on!");
try {
Class driverClass =
java.lang.Class.forName("com.apple.spell.ui.JTextComponentDriver");
Method checkMethod =
driverClass.getMethod("startRealtimeChecking",new
Class[]{javax.swing.text.JTextComponent.class});
checkMethod.invoke(spellOne, new Object[]{one});
checkMethod.invoke(spellTwo, new Object[]{two});
} catch (Throwable t) {
t.printStackTrace();
}
} else {
System.err.println("turning off!");
try {
Class driverClass =
java.lang.Class.forName("com.apple.spell.ui.JTextComponentDriver");
Method checkMethod =
driverClass.getMethod("stopRealtimeChecking",null);
checkMethod.invoke(spellOne, null);
checkMethod.invoke(spellTwo, null);
} catch (Throwable t) {
t.printStackTrace();
}
}
realTimeChecking = c;
}

public void
toggleRealtimeSpellcheck() {
setRealtimeSpellcheck(realTimeChecking ^ true);
}


public static void main(String args[]) {
new SpellTest();
}

}
