Clicking http://www.java.com/en/download/installed.jsp causes Firefox to freeze.  I have to kill it with the Task Manager.  The problem does not occur in Firefox 3.0.10

Reproducible: Always

What's your OS, matti?  The five other reports confirming this problem in the Mozillazine topic [url=http://forums.mozillazine.org/viewtopic.php?f=9&t=1293885]FF 3.0.11 freezes with Java[/url] are all using Windows XP or Windows 2K using Java 1.6.0_13 or Java 1.6.0_14.  One Vista user reported no problem.
win2003 (xp,2003,vista,7,2k should not matter) and I retested with FF3.0.11, also no freeze.

Did you all tested in the safemode and/or a new profile ?
In that case use http://developer.mozilla.org/en/docs/How_to_get_a_stacktrace_with_WinDbg with !analyze -v -hang
This is in a brand new profile.  I upgraded from Java
1.6.0_13 to Java 1.6.0_14 a few days ago with the Java updater.  "Java Control Panel > Advanced > Java Plug-in > Enable the next-generation Java Plug-in" is not ticked.  (But the freeze occurs even if it is ticked.  After a browser restart, of course.)

It looks like it's probably a JavaScript problem rather than a Java one.  If I disable JavaScript with Tools > Options, then the freeze does not occur on the URL I supplied.  Instead, the web page displays a message that JavaScript must be enabled.  None of the Java testing sites I've gone to indicate any problem.  I'm editing the bug title to reflect that it appears to be the site that's freezing Firefox 3.0.11 and Firefox 3.0.12pre on Windows XP, not Java.
Summary: Firefox 3.0.11, 3.0.12pre freezes with Java → Firefox 3.0.11, 3.0.12pre freeze on java.com
The freeze does not occur if I use the Add-ons manager to disable the Java Deployment Toolkit 6.0.140.8 plug-in.

Could it be a mimetype problem that has finally manifested in Fx 3.0.11?  This Sun bug report last modified Jan 2009 says they were going to change it to prevent a possible collision with a Mozilla internal mimetype, but it looks like Sun didn't change the mimetype of this plugin after all.

I can confirm the freeze after clicking on the affected URL link, and that disabling the "Java Deployment Toolkit 6.0.140.08" allows the page to load correctly. This is on two Windows XP sp3 machines using firefox 3.0.11. This issue wasn't present in firefox version 3.0.10

This may or may not be related to this bug from SDN:
http://bugs.sun.com/bugdatabase/view_bu ... id=6729238
Sorry broken link above, but its the same as in the previous Comment(#11)
Currently back on 3.0.10.with no issues.

Exactly the same freezes with 3.0.11 on these links.

^On Windows XP sp3.
Since this problem does not exist in Firefox 3.0.10, I've added regression to Keywords.  I'm afraid I don't have the Internet bandwidth to find the regression window.  Would one of the other commenters be able to do this?  It might facilitate a fix.

new based on the dupe.
We still need a windbg trace of the hang
Status: UNCONFIRMED → NEW
Ever confirmed: true
Do you have this hang only on java.com or similar? Since I installed fx 3.0.11 I've got a lot of hangs on many sites (http://www.atpworldtour.com/, http://www.sonyericssonwtatour.com/) and it seems related to flash content (I've been recently using Flash player 10.0.22.87). It happens both in safe-mode and normal mode. 
Has anyone experienced the same troubles ? I've got a windbg trace of the hang, shall I post it here or in a new thread, since this one seems related to a Java issue ?
This appears to happen on ANY website which accesses the Java Deployment Toolkit (http://java.com/js/deployJava.js).
Also, it appears to ONLY occur on Windows XP (and possibly Windows 2000, according to some reporters).
Windows 2003 and Vista do not exhibit this problem.
I can confirm that disabling the following plugin fixes the problem without adversely affecting most other javascript functionality.

Java Deployment Toolkit 6.0.140.8

    File name: npdeploytk.dll
    NPRuntime Script Plug-in Library for Java(TM) Deploy
Al: Can you confirm this on Windows 2000 or XP?
Also: If we can get a regression range from someone using 3.0.11pre builds, that'd help a lot.

The only possibly similar bug I can think of is bug 489988... Olli?
We have the same problems with our Applets. 3.0.10 works fine and 3.0.11 doesn't load the Applets.
Win XP SP2
JRE 1.6.0_14

Navigating to : java.com/en/download/installed.jsp freezes the browser and the process needs to be killed using task manager. Tried on a Windows Vista and it seems work without any problems.

This is verified on Windows XP. Running Firefox 3.0.11 with the Java 1.6.0_14 causes a hang on
This is verified on Windows XP. Running Firefox 3.0.11 with the Java 1.6.0_14 causes a hang on http://www.java.com/en/download/installed.jsp. Doing the same with Firefox 3.0.10 does not hang.
I've attached another stacktrace. Not sure if it is usable though since I've never done it before.

I furthermore can confirm that this bug happens when http://java.com/js/deployJava.js. Is being used. This is quite bad since it actually is the Applet and Webstart deployment technique officially recommended by SUN (and thus used quite often). Sucessful execution of this script should be a prerequisite for any RC.
Alright. We need a regression range.

Anyone who sees this, please use the following link to download the "mozilla1.9.0" builds and see when this regressed:

http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2009/

It's important to know when so we can determine what caused this.

We probably don't need anymore Windbg stacktraces, but thanks to everyone for providing them.

The hang doesn't happen on all Java applets, as I've found through looking around.
I do notice on games on nintendo8.com, I get the following error and the applets don't run:

For the record, this doesn't happen with 3.5 / 1.9.1 branch.
The best URL at least for me is: http://browserspy.dk/java.php

Samuel, I can clearly reproduce it with Firefox 3.0.11 but not with the latest Shiretoko and Minefield nightly builds. But opening this page with a debug build of Minefield also constantly gives me the assertion. So I wonder if 1.9.1 is affected too. I don't have a debug build for Shiretoko yet. Have to build one before. :(

I do not crash loading that one -- what did you modify? If it doesn't affect functionality maybe we could get Sun to modify the live copy at http://java.com/js/deployJava.js
I changed this:

for (var i = 0; i < plugin.jvms.getLength(); i++) {
                  list[i] = plugin.jvms.get(i).version;
}


To this:

var jvms = plugin.jvms;
for (var i = 0; i < jvms.getLength(); i++) {
                list[i] = jvms.get(i).version;
}
The current working theory (based on your change) is that this is a regression from bug 487204. Trying to make a debug build to test this theory.

The patch in bug 487204 is pretty simple and self-obviously unharmful, but it may be exposing some bug elsewhere or in the plugin itself.
Blocks: 487204

So this is also on trunk and 1.9.1. JFI I can see the same assertion on 1.9.1 too.
We need to block on this one way or another for 1.9.0.12. Not sure if we need to fix the assertion on 1.9.1/1.9.2, but flagging for that as well...

> Maybe bug 456705?

I wouldn't say so. I'm trying to reproduce with debug build of 3.0.12pre, no luck. I can see the assertion failure only. The variant passed looks like a completely broken instance.

There is a tryserver build available without the JS patches at:

I tried this build on Windows XP and everything works. No hang anymore when loading the browserspy page.
That tryserver build backed out both Bug 426520 and Bug 487204.
We are not hanging on that assertion or an invalid variant type. We hang in HeapFree when a broken variant presents it self as NPVariantType_String. I figured out that in release mode we get lot's of broken variants passed to this function. Looks like we ignore some failure result when getting/creating a variant. I haven't seen a variant being released twice or something like that.

There is probably no way to get symbols for npdeploytk.dll, isn't it?
 
Just FYI... the bug in question disappeared yesterday, but re-appeared today.  Still works fine in IE8.
Moving to the JS component. We really need an owner here.

I debugged the npdeploytk.dll with source code.
In npdeploytk.dll, it calls NPN_InvokeDefault() on an NPObject that returns a
bool to a result variant. For some reason, after successful
NPN_InvokeDefault(), the variant is not received the right result which is
supposed to be a boolean variant. 

A workaround is to set the result variant to void before NPN_InvokeDefault()
call. This seems to fix the hang problem
I don't see how this is JS -- sounds from the bug like it's in our plugin code's handling of variants?

npdeploytk.dll is part of Sun's JRE. Sun is probably going to patch it in the next update release and code more defensively in npdeploytk.dll to avoid such issues.

In the meantime, we need help from Mozilla to understand why NPN_InvokeDefault(NPP npp, NPObject *npobj, const NPVariant *args, uint32_t argCount, NPVariant *result) call does not set the return value to the result variant. It used to work before FF 3.0.11.
Hao: Josh can probably help with that. Josh?

Is there any way you can update the JS on java.com with the changes in comment 44? There's no difference functionally and it should solve a bunch of sites that include that file.
It appears that the Sun folks have already updated deployJava.js to include my suggested change:

http://java.com/js/deployJava.js

I have also updated my Java detection site at:
http://www.pinlady.net/PluginDetect/JavaDetect.htm

But you may have to clear your browser cache before visiting any Java sites that crashed Firefox, to make sure you are getting the updated js.
Confirming the assertion failure is gone. We have no more a test case.
What about browserspy.dk? Has it been changed too?
The following still crashes (after clearing cache):

http://pluraserver.com/?affiliate=a1653b46-efe9-ac95-d977-121844725f45&cpu=0.7

It works fine in 3.5.
I don't have a Windows environment to debug this so I can't help much right now.

Hao - interesting that setting the result to void before the InvokeDefault call helps, because after checking for a valid context, object, and result pointer we set the result to void - "VOID_TO_NPVARIANT(*result);".
Attached patch try this, v1.0 (obsolete) — — Splinter Review 
This patch is based on my reading of Hao's comments and our source code, I have not done any debugging whatsoever. Can somebody tell me if this patch gets rid of the hang? We wouldn't want to take this patch exactly but for a test it should work fine.
I try to make a minimalized version. Here is a first version:

http://web.inter.nl.net/users/L.B.Kruijswijk/ffjavadetectcrash.html

It is not yet finished. Code is obfusicated, so it takes some effort.

It hangs immediately in 3.0.11 and not in 3.5.

Note, that this crashes only in the detection of Java. It does not actually
start Java. In 3.5, I don't see any start of Java in this simplified version.

Here is the original deployJava.js that crashes Firefox 3.0.11:

http://www.pinlady.net/tmp/original_DeployJava.js.html


Here is the modified deployJava.js that should not cause any Firefox crash:

http://www.pinlady.net/tmp/modified_DeployJava.js.html
This is the minimum script I could make (it is also on the site, 2 posts earlier):

<html>
<head>
</head>
<body>
<script type="text/javascript">

// Minimum crash script for Firefox 3.0.11.

var div=document.createElement("div")
document.body.appendChild(div)
div.innerHTML="<object type=\"application/npruntime-scriptable-plugin;DeploymentToolkit\"></object>"
var obj=div.firstChild
var len=obj.jvms.getLength()
for(var x=0;x<len;x++){
    obj.jvms.get(x)
}

</script>
</body>
</html>
When I look to the fix of #44, then it is the multiple 'obj.jvms' that is killing.

You can even further simplify the script as follows:

var div=document.createElement("div")
document.body.appendChild(div)
div.innerHTML="<object type=\"application/npruntime-scriptable-plugin;DeploymentToolkit\"></object>"
var obj=div.firstChild
for(var x=0;x<10;x++) obj.jvms

However, if I unroll the loop, it won't crash anymore.
Attached patch v1 (obsolete) — — Splinter Review 
I'm enable to reproduce with the scripts you provide.

I'm able to reproduce on browserspy.

This is fixing the assertion failure and also the crash/hang.

v1

I'm fine with doing this to work around this problem, but I'd prefer to do this only for this particular plugin rather than doing this for all plugins and letting them start depending on this workaround.

Sun still needs to fix the bug in the plugin, to not ever return success here w/o properly initializing the out param etc, but I doubt that fix will be available before 3.0.12 goes out, so I think we should go ahead and work around this.

I'll attach a modified version of Honza's fix here.

Honza's fix, but isolated to this plugin only.

Maybe add parenthesis around the strcmp == 0 so precedence is more obvious.

    
    

    
  
Precedence of == against && is usually not misunderstood, but perhaps the issue here is that long string literal, pushing the == 0 way over? If so a single-use static const char kMagicMimeType[] = "..." constant might help.

Approved for 1.9.0.12, a=dveditz

We definitely want this for the 1.9.0 branch. We probably want to land on the 1.9.1 branch too just in case the same broken plugin causes problems there, too. I'm assuming you don't want this on trunk, otherwise we could have gone with the simpler v1 patch and fixed any future broken plugins too.

We should file a new bug to track the removal of this hack once Sun has fixed it in an upcoming version of Java.
