On my work PC, Shiretoko will crash the moment a java applet starts to load if either IE Tab 1.5.20090207 and/or NoScript 18.104.22.168 are installed and enabled. This only happens in the Shiretoko 20090517 and later versions. Neither Firefox 22.214.171.124 nor the trunk nightlies will crash. It makes no difference if JIT is enabled or not. My work PC has java version 1.6.0_02 on it. I can't update the java version on my work PC so I'll need to test my home PC to see if this is a problem with the latest version of java or not. Seeing how I'm seeing reports of the same crash on the Crash Stats site and a number of them mention java, I'm guessing the java version may not matter. Here's the crash dump in Shiretoko 20090521. It's pretty useless though since it just lists js3250.dll@0x6a3f4 as the crash address. The crash address is consistent as the crash always occurs @0x6a3f4 in the 20090521 release. Each release has a different crash address. http://crash-stats.mozilla.com/report/index/f15c0467-18ac-4057-ba1f-312ce2090521 Since the problem in the Shiretoko 20090517 load, the problem had to be caused by something checked in 20090516. That would be one of these: http://hg.mozilla.org/releases/mozilla-1.9.1/pushloghtml?startdate=May+15%2C+2009&enddate=May+17%2C+2009 I tried to find an existing bug report on this since the problem does not occur in the Trunk nightly loads and I figured it might have been fixed already, but was unable to do so. I also tried older versions of Minefield and could not reproduce.
Could use help with a regression range on TM, and testing with more configs.
Tried to reproduce this with Shiretoko 20090521 on Ubuntu 9.04 32-bit with No-script 126.96.36.199 using JRE 1.6.0_13. Does not crash. Maybe Windows only?
WFM on build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:188.8.131.52) Gecko/2009051909 Firefox/3.0.11 (.NET CLR 3.5.30729) ID:2009051909 with IE Tab plugin and Java 1.6.0_13
I can't reproduce that crash on windows XP with Shiretoko nightly from 20090517 using Noscript 184.108.40.206 with Java Plug-in 1.6.0_11 Nor was I able to reproduce with IE Tab 1.5.20090207 added to the above The older Java Plugin version is looking like the culprit.
Confirmed: Crash on Java version 1.6.0_02 with the same build Id and IE Tab plugin.
It looks like this is most likely only an issue with older versions of Java. Unfortunately I'm not an administrator on my work PC so I can't upgrade the Java version to test this out. I can test it on my home PC later today. It's curious though as to why this only affects Shiretoko and not Minefield. I found a few crash reports for Shiretoko 20090520 with different java versions of java.dll, but the latest one I could find is 220.127.116.11 (possibly version 1.6.0_07): http://crash-stats.mozilla.com/report/index/7da8d78d-a9a7-48a6-b197-2da4c2090521 http://crash-stats.mozilla.com/report/index/ce079ba6-37d9-40fa-bd83-ff8b42090520 http://crash-stats.mozilla.com/report/index/488224f8-b9bb-49db-9696-4f0252090521 18.104.22.168 (guessing version 1.6.0_03): http://crash-stats.mozilla.com/report/index/3ef5aff2-cae9-4991-bd17-eca332090520 Here's mine with version 22.214.171.124 (java 1.6.0_02): http://crash-stats.mozilla.com/report/index/80ccb60b-89fc-4192-aab8-545402090521 I'll need to check what the latest version of java.dll is when I get home. It's possible this is a non-issue with JRE 1.6.0_13 and realistically every one should upgrade to that, but sometimes it's not possible, like in my case. I've told the IT guys they should upgrade Java for security reasons, but they haven't bothered to do it. In the mean time here are two crash addresses in case anyone wants to look them up on Crash Stats: Shiretoko 20090520: js3250.dll@0x6a246 Shiretoko 20090521: js3250.dll@0x6a3f4
If I let http://java.sun.com/applets/jdk/1.4/demo/applets/Clock/example1.html in the config mentioned in comment #4 then let it run for a while, 10-15 minutes later Firefox crashes. However, crash reporter doesn't fire. hmmmm?
Found the regression range: any version of java before 1.6.0_07 (not including) either hangs the browser or crashes it in this case. I'm removing the qawanted keyword and adding relnote for a nomination to take care of users with older versions of java.

What's the offending commit in _our_ code, though -- this worked prior to 20090517 and works on the trunk now, so it seems like we can fix it ourselves too?

No, there are like 100 commits in there, many of them in the JS engine. We need to know which of those (using tracemonkey hourlies might help) to know how to fix the issue in our side on 1.9.1.x. Alternatively/additionally, we want to know which of the commits that's now on trunk fixed it. That would let us work from the other side.
I used the hourly releases from http://hourly-archive.localgho.st/hourly-archive2/mozilla-1.9.1-win32/ and narrowed down the regression range. Good: 1242494055-20090516101415-df1677120450-firefox-3.5b5pre.en-US.win32.zip Bad: 1242499556-20090516114556-a1319ee53a74-firefox-3.5b5pre.en-US.win32.zip So that means the problem was caused by one of these: http://hg.mozilla.org/releases/mozilla-1.9.1/pushloghtml?fromchange=df1677120450&tochange=a1319ee53a74
Are there localghost hourlies for tracemonkey? That's a pretty huge regression range still. :-/
I don't know. The only reason I knew about that site was because someone posted a link to it in bug 494199, which also needs local hourlies for tracemonkey.
Summary: Crash in js3250.dll when java applet loads if IE Tab or Noscript extensions are installed. → Crash in js3250.dll when java applet (java plugin older than 1.6.0_07) loads if IE Tab or Noscript extensions are installed.
Are the hourlies still available somewhere?
There are only http://hourly-archive.localgho.st/win32.html, but it doesnt archive back to may 17th. I guess my question remains: we know the regression build from comment 10, we have the list of testcases in this bugs's URL and the list from bug 494977, and we have the wide regression range from comment 0. Given that hourly builds dont trace that far back, what are other things we can do to help get you what you need?
We could use hg bisect to get the patch which caused this. I could do this tomorrow morning (in around 5h). We have a VM ready for that from the QA storage. Al will this be working OOTB?
Can somebody please tell me where I can download the Java6u3 installer? I cannot find any website which offers this old version. Every page redirects to the latest installer. :/
Nevermind, got it via IRC really quick: http://java.sun.com/products/archive/
Ok, I'm able to reproduce the crash with latest Shiretoko on Vista. Running the nightly build in parallel with WinDBG shows me the following output: command window ============== (a14.e0c): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling.

That means I blame bug 491126 (Sharing object map for fast array instances) to be the cause here. CC'ing Igor and Brendan to this bug.

No idea if we need to block here but for safety lets ask.
Bug 491126 is also in the trunk though and it doesn't look like any of those files have been changed since the fix for bug 491126 landed. Any idea why the fix for bug 491126 would crash Shiretoko, but not Minefield?
(In reply to comment #27) Probably because this bug is related to LiveConnect to old plug-in. I could reproduce this using 1.6.0_13 when I unchecked "next-generation Java Plug-in" in Java Control Panel. Minefield has removed a support for LiveConnect to old plug-in (see bug 485984). Unfortunately it will not be acceptable to 191 branch, of course.
I'm guessing the "fix" then is to basically add a release note telling users to upgrade to the latest version of Java or to disable the java plug-in for those of us who can't. I'm curious if this is also a problem with Java 5.0. I'm guessing it would be.
Isn't backing out bug 491126 an option?
The bug is a regression from the bug 489501 - I forgot to check for native objects in js_SetProtoOrParent. The bug 491126 just exposed that.
Created attachment 380248 [details] [diff] [review] fix v1 The patch adds the missing check for a native object in js_SetProtoOrParent when making sure that obj owns the scope.

Comment on attachment 380248 [details] [diff] [review] fix v1 This function returns JSBool, so it should return JS_FALSE on error.

Wouldn't it be cleaner if it was a JSBool?
(In reply to comment #35) > because you need "!!" just to coerce it right? Wouldn't it be cleaner if it was > a JSBool? No: !! is necessary to convert JSBool into bool without warnings. The compiler does not see that JSBool value can have only 0 and 1 as values so it can not simply treat the bits stored in JSBool as bool. A good compiler warns about that. On the other hand the implicit conversion from a boolean (especially from true/false compile-time constant) into int is trouble-free.
In particular, we have true and false nicely used all over jstracer.cpp and some other new-ish code, but we're forced to keep using JSBool FASTCALL return types, for ABI reasons. No warnings from return true or return false in such a function. /be

Comment on attachment 380248 [details] [diff] [review] fix v1 Construing sayrer's point narrowly misses the fact (also not visible in the patch's context) that the other two returns use JS_TRUE and JS_FALSE. It seems better to use JS_FALSE (or ok) than to mix false in one third of the returns of literal boolean value-codes. r=me with that nit addressed. /be
pushed to TM with an extra change to use good old JS_FALSE in place of all too modern false: http://hg.mozilla.org/tracemonkey/rev/a3dcea4508e6
