225102 - 1.6 Mozilla breaks Java for all other installed mozillas. firebird.reg fixes it, but why ?

Status: RESOLVED EXPIRED

(SeaMonkey :: General, defect)

Description

[Joachim Otahal]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20031030
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20031030

I hav Mozilla 1.2.1/1.3/1.4.1/1.5/1.6a installed parralel on my system, each one
using it's own subdirectory of course. With Mozilla 1.6 java wasn't recognized
any more, showed up in about:plugins. Java then didn't work with any of the
older versions of Mozilla too.
I had to import the firebird.reg to make it work, probably the
[HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org\Mozilla]
"CurrentVersion"="1.5" 
was needed.

But why ? And why does this break Java for all older Versions of Mozilla on the
machine ? This strangeness did cost me quite some time on 3 Machines.


Reproducible: Always

Steps to Reproduce:
1. Remove HKEY_LOCAL_MACHINE\Software\Mozilla, check about:plugins to verify java.
2. Use 1.6a build on
http://www.heise.de/security/dienste/browsercheck/tests/java.shtml
3. Java is not started. it shows "click here for plugin", although the .dll
helpers are at the right place.

Actual Results:  
Nothing.

Expected Results:  
Website should say "Java ist AKTIV!" without hacking 'round the registry before.

Addendum:
HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org
has to be removed to reproduce.
[HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org\Mozilla]
"CurrentVersion"="1.5" 
Makes java work _without_ restarting mozilla, just page reload is enough.

[HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org\Mozilla]
"CurrentVersion"=""

Note that the value can even be empty, and java works.
removing/renaming the CurrentVersion registry entry disables Mozilla-Java.
