Bug 105073 – Java Applets don't load with Firefox 1.0.6

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Wolfgang Illmeyer 2005-09-06 15:11:45 UTC]

Firefox refuses to load any applets using sun jre. instead, java throws an
exception. Reverting back to Firefox 1.0.3 solves that problem, I'm not sure
about the versions in between though.

see http://forums.gentoo.org/viewtopic-t-366722-highlight-.html for a detailed
description

Reproducible: Always
Steps to Reproduce:
1. install firefox 1.0.6
2. install sun jre
3. open a page containing an applet with firefox

Actual Results:  
the java console shows an exception:

java.lang.ClassNotFoundException: GetHost.class <-- contains the applet

I cannot comfirm this bug.
I use Firefox version 1.0.6-r5 and have created a symlink to my jre as the
official SUN guide suggests:

The last version I could confirm the bug with was 1.0.6-r2, an update to
1.0.6-r5 solved the problem for me.
