182106 - Mozilla should disable the JRE scan flag by default

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Java: OJI, defect, P2)

Description

[Xiaobin Lu]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
Build Identifier: 20021126

Since Mozilla 1.0(Netscpae 7.0) release, Mozilla put JRE scan by default. This 
creates some issues as described below:
1. JRE installer will copy Java Plugin files into Mozilla plugins directory 
since 1.4.1 release.
2. If the user install 1.4.2 later, since the scan is enabled, Mozilla will 
also register 1.4.2 as plugin.
3. Since Mozilla OJI plugin is not designed to support multiple JRE, so crashes 
can not be avoided sometimes.



Reproducible: Always

Steps to Reproduce:
1. Install JRE 1.4.0, copy plugin dll file into Mozilla plugins directory.
2. Install JRE 1.4.1, select customize installation, not register Netscape 6
3. Start browser, visit some applet requires 1.4.1 plugin, the browser will 
crash.

Actual Results:  
Browser crash.

Expected Results:  
No crash

The fix is to comment the prefs("plugin.scan.SunJRE", 1.3) in winprefs.js.

We can not take out this pref without a new way for Java to work out of the box
if installed before the browser we have the "first install problem". Since JRE
1.4.2 is being installed AFTER the browser, why can't the installer simply
delete the 1.4.1 DLLs from the Mozilla plugin folder?

Whenever this pref is removed, please test and verify that Java still works out
of the box when it is installed *before* the browser. Please test a ZIP of
MFCEmbed to verify Java works like before.

Mass-closing bugs in the "OJI" component: OJI plugin integration was replaced with npruntime long ago, and these bugs appear to be irrelevant now. If there is in fact a real bug that remains, please file it new in the "Core" product, component "Plug-ins".
