143657 - Mozilla 1.0 RC2 Will Not Start, Java Plugin Error

Status: VERIFIED DUPLICATE of bug 19118

(Core Graveyard :: Plug-ins, defect, P3)

Description

[charlie]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
BuildID:    2002051006

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc2) Gecko/20020510

Fresh install of 1.0RC2.  Removed old install first.  Install goes fine.  Then 
when starting Mozilla FIRST TIME, start fine.  Close Mozilla (and startup 
agent) it WILL NOT START SECOND TIME.

Exact Error Popup:
Title of Window "Java Plug-in Proxy Configuration"
Contents of Window" Unable to obtain proxy configuration from Netscape 
Navigator 3.x - fallback"

Click "OK" and get "Mozilla.exe has generated errors and will be closed by 
windows."

SPECIAL NOTE:  If I delete the "prefs.js" file from the Application 
Data/Profiles/Default user prof folder then Mozilla will restart fine.  Mozilla 
of course then generates a new prefs.js file, standard, and works fine for 
current session but again will not restart.  Same cycle, same errors, 
reproducible every time. 




Reproducible: Always
Steps to Reproduce:
1.  Install 1.0RC2 Windows Talkback
2.  Start Mozilla
3.  Stop Mozilla
4.  Start Mozilla again, ERROR HERE

Actual Results:  Exact Error Popup:
Title of Window "Java Plug-in Proxy Configuration"
Contents of Window" Unable to obtain proxy configuration from Netscape 
Navigator 3.x - fallback"

Click "OK" and get "Mozilla.exe has generated errors and will be closed by 
windows."


Expected Results:  Started

Which JRE version Do you see in help/About:plugins ?

Comment 2

[charlie]

Multiple JREs present (was not aware that JREs were picked up, thought I was 
starting fresh with fresh install, I checked the Mozilla plugins directory and 
none exist there but they are being found and imported from JavaSoft JRE bin.)

JRE 1.2.2
JRE 1.3.0
JRE 1.3.1

are all listed multiple times at various points in help:About plugins.

I removed them from the JavaSoft JRE locations and now Mozilla does start (of 
course no Java support, but starting at all is an improvement.) 

I have multiple JVMs on my machine because I am a Java developer and at various 
times need various JVMs for projects (some have older JVM dependencies, etc.) 

Again, I had assumed that Moz was not importing plugins automatically but 
rather the plugins would be contained in the moz plugin dir, I thought I had no 
JRE installed and was using a fresh moz install (I was, but again, the import.)

-> Plugins

There are many problems with the automatic plugin scans.
The plugin people can tell you the way to disable this plugin scan.
(and I need this for 3 other bug reports)

Could you attach a diff of your prefs.js with a copy regenerated after you
delete it and another after you can not startup again?

Does running in a new profile help?

The newest JRE should be "scanned" from its installation location. You can
disable this feature by commenting out this line in winpref.js:
pref("plugin.scan.SunJRE", "1.3");

I dont have a diff of the prefs.js but let me explain.  There is no diff because
the BEFORE is NO FILE -->  the AFTER is the new generated entirely by Moz file.
  I had about 3 lines in it as I recall from looking at it (I no longer have
it.) I am speaking of DELETING it entirely, then it starts, then try to restart
(with prefs file just created by moz, same file, no changes to preferences made
by user, etc) and it hangs with the aforementioned error.  

I did delete all the JVMs as stated in a previous comment and now moz starts and
restarts fine (and therefore I do not have the problem any longer and dont have
a fresh prefs file, etc.)  JVMs were in there proper locations.  (ie some
located at JavaSoft/JRE/1.2.2/bin and JavaSoft/JRE/1.3.1/bin and
JavaSoft/JRE/1.3.1_01/bin etc.) All were apparently automatically imported and
were imported multiple times (same JVM was shown more than once, in its own box,
in about:plugins.)

assigning to peterl, plug-ins scan

Comment 7

[rubydoo123]

reporter: what do you have your start page set to? Does that page contain any java?
(see Edit|Preferences|Navigator) and set When Navigator starts up, display: Blank.

Also, have you modified any of the files or is this from a clean install? Can
you completely uninstall mozilla, install a new version without making any
changes to the application and try this again.

A plug-in manager would help adjusting for plugin mappings problems.
