STEPS TO REPRODUCE:
1] Please visit URL mentioned above.
2] Enter something in text-Box.
3] Click button "Upper" & then click button "Lower"
EXPECTED RESULTS:

ACTUAL RESULTS:

DESCRIPTION:
The methods upper and lower are in Applet, and are being called from Javascript.
Here is applet code:
########## APPLET CODE START ###########
import java.applet.Applet;
import java.lang.*;
import netscape.javascript.JSException;
import netscape.javascript.JSObject;
public class simple_applet extends Applet
{
JSObject win, doc, form, field;
public void init()
{
// BE CAREFULL : the form must have been define before the applet starts
// --> <APPLET> tag must be embeded after the form
win = JSObject.getWindow(this);
doc = (JSObject)win.getMember("document");
form = (JSObject)doc.getMember("the_form");
field = (JSObject)form.getMember("the_field");
}
public void upper()
{
String text = (String)field.getMember("value");
System.out.println("Text = " + text);
field.setMember("value", text.toUpperCase());
}
public void lower()
{
String text = (String)field.getMember("value");
System.out.println("Text = " + text);
field.setMember("value", text.toLowerCase());
}
}
############# APPLET CODE END ####################

Confirming bug with debug Mozilla build 2001-0322 on WinNT.
The testcase works fine in NN4.7, but in Mozilla you get this error
in the JavaScript Console:
JavaScript error:
line 0: uncaught exception: java.security.PrivilegedActionException
<<java.lang.reflect.InvocationTargetException>>
Reassigning to OJI, and cc'ing some of the people looking at recent
bugs like this. I think this is a duplicate of one of them, but I'm
not sure which. Perhaps bug 59447? bug 61488? bug 59983? etc. etc.

I would encourage people evaluating this bug to also look at the /MUCH/ simpler
test case I provided at the URL for bug 61488. That test case involves only
communication from Javascript->Java and contains no references to JSObject.
