User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

I maintain the Firefox extension "openinfocard" http://code.google.com/p/openinfocard/downloads/list
Since Firefox3 users experience an error message "ReferenceError: java is not defined". Today I tried whether this error still occurs with jdk-6u10-rc-bin-b28-windows-i586-p-21_jul_2008.exe and ran into the error message.
"TypeError: invalid 'instanceof' operand java.net.URLClassLoader" here:
http://code.google.com/p/openinfocard/source/browse/trunk/firefox/components/TokenComponent.js#272
This works with previous version of java.

Reproducible: Always

Steps to Reproduce:
1. Install the Firefox extension into FF3. Save to disk, then install.
2. navigate to a site that uses Information Cards e.g. https://wag.bandit-project.org/BanditIdP/index.jsp
3. Click on the Information Card icon
Actual Results:  
An alert dialog opens with the error message "TypeError: invalid 'instanceof' operand java.net.URLClassLoader

Expected Results:  
No alert but the identity card selector window opens and you can create an information card (self-issued) that you can then use to provide your claims about yourself.

Still does not work in 3.6.8.
Your user agent is: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10

I found a simpler test:
- open the console and enter
  "alert(window instanceof java.net.URLClassLoader)"
- Fehler: invalid 'instanceof' operand java.net.URLClassLoader
Quelldatei: javascript:%20alert(window%20instanceof%20java.net.URLClassLoader)

When I try 
 alert(window instanceof java.net.URLClassLoader)
on Minefield I get the message "java is not defined" although the java console starts.

Mozilla/5.0 (Windows; Windows NT 6.1; rv:2.0b3pre) Gecko/20100730 Minefield/4.0b3pre

The java version is 1.6_u18.

Retried this 
 alert(window instanceof java.net.URLClassLoader)
in 
 Mozilla/5.0 (Windows NT 5.1; rv:2.0b13pre) Gecko/20110223 Firefox/4.0b13pre

The java console shows and in the error console of Minefield I get:
Error: java is not defined

Reporter -> Are you still experiencing this issue with the latest version of Firefox 5? Does the issue occur with the latest nightly? http://nightly.mozilla.org/

When I enter "alert(window instanceof java.net.URLClassLoader)" in the console's code field in Aurora 6.0a2 (2011-0621)
I get:
 Error: invalid 'instanceof' operand java.net.URLClassLoader
 Source File: javascript:%20alert(window%20instanceof%20java.net.URLClassLoader)
 Line: 1

Did you try this one-line test on your platform and it worked? If not please set the status to confirmed.
