User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b4) Gecko/20100818 Firefox/4.0b4
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b4) Gecko/20100818 Firefox/4.0b4

Live Connect is broken. The globals "java" and "Packages" are not defined. 
 
See https://developer.mozilla.org/en/java_in_firefox_extensions for how it worked in 3.X.

This regression breaks all Firefox extensions that use java. Bug could also go to "Extension Compatibility". 

Live Connect issues just keep coming back every major release:(


Reproducible: Always

Steps to Reproduce:
1. Open Web Console
2. Type alert(java);
Actual Results:  
Error: java not defined

Expected Results:  
Java defined

Have you read https://developer.mozilla.org/en/LiveConnect and https://jdk6.dev.java.net/plugin2/#LIVECONNECT ?

The old liveconnect is gone

Even if deprecated by Sun specs, the "java" and "Packages" globals were still functional in 1.9.X (up to FF 3.6) and the MDC docs are full of examples using them. 
 
https://developer.mozilla.org/en/Core_JavaScript_1.5_Guide/LiveConnect_Overview

The Sun spec has only code snippets that work with an applet, so I guess the idea is to include a html applet in XUL when using LiveConnect in FF4 extensions? 

Can you confirm that applets are mandatory? If so I hope someone fixes the MDC docs. 

In any case, extensions like FireGoose or PiggyBank are currently broken in FF4:

The liveconnect change happened in Gecko1.9.2 and that is FF3.6.x and it should not be the cause if it works in FF3.6.x

I can confirm that I get an error with Firefox 4.0b4:
Fehler: java is not defined
Quelldatei: javascript:alert(java);

but it works (!) with Mozilla/5.0 (Windows NT 6.1; rv:2.0b5pre) Gecko/20100830 SeaMonkey/2.1b1pre and Next Generation Java Plug-in 1.6.0_21 for Mozilla browsers

I get an "Java Package "java"] " alert

Why has this been moved to the "Core Graveyard" component? 

It's needed for java in Firefox extensions.

If support for the java/Packages globals is to be dropped at least change the misleading docs @mdc.
