User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.9a8pre) Gecko/2007090704 Minefield/3.0a8pre

There are several Java-related crashes when AdBlock Plus is installed.

Here's another one.

Steps to reproduce:

With AdBlock Plus installed, go to http://www.java.com/en/download/installed.jsp and click on the green "Verify Installation" button.

Reproducible: Always

Steps to Reproduce:
1. Have AdBlock Plus 0.7.5.1 installed (filter settings do not matter)
2. Go to http://www.java.com/en/download/installed.jsp .
3. Click the green "Verify Installation" button.
Actual Results:  
Crash with Breakpad trigger:

http://crash-stats.mozilla.com/report/index/3d3753e3-5d5e-11dc-a943-001a4bd43ef6
(just two examples)

Expected Results:  
The result of the Java installation verification process should be shown.
Expected is information if you have the most recent version of Java installed.

Regressionwindow:

Works in 20070905_1328
Broken in 20070905_1344 

Can be circumvented by de-installing AdBlock Plus (de-activating only does not help!)

from above regressionwindow

http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=PhoenixTinderbox&branch=HEAD&branchtype=match&filetype=match&whotype=match&sortby=Date&hours=2&date=explicit&mindate=1189024080&maxdate=1189025039&cvsroot=%2Fcvsroot

-> bug 393845 ?

Another testcase:

1. Go to http://www.screencast-o-matic.com/watch/ciiXQIZy
2. Wait for the Java applet to load (the Java logo is shown and then it disappears).
3. Firefox crashes.(unfortunately no Breakpad because it came up but it did not work this time, using 20070905_1344 - perhaps Breakpad is broken in that build)
Regressionwindow checked, it's the same as above:
Works in 20070905_1328
Broken in 20070905_1344

Seems that Breakpad only works from time to time, got a "fresh" report now:

Fwiw, the Java plugin itself probably has some major issues itself.
I get this same crash when loading the testcase I attached in bug 275783, https://bugzilla.mozilla.org/attachment.cgi?id=279607
then loading a different site and then going back.

Attachment: testcase

Not sure, but this is probably the same issue as what happens in combination with Adblock Plus.
This is crashing for me (can someone confirm, I don't have the right Java version currently)

Attachment: testcase2

This time using embed to invoke the Media Player, which is also crashing for me, after the patch for bug 393845 landed.

Comment 7

[Gerd]

I think that the crash is independent from the Java version installed (just did not have the time to verify this).

Comment 8

[Jonas Sicking (:sicking) No longer reading bugmail consistently]

Biesi: could this be a regression from your fix to bug 393845

Comment 9

[Martijn Wargers (dead)]

Another site that crashes directly after a reload for me:
http://www.knbc.com/videostream/10954229/detail.html?treets=la&tml=la_break&ts=T&tmi=la_break_1_08350209242007
This also regressed when the patch for bug 393845 was checked in.

This should be fixed by the backout of bug 393845
