498399 - Java applet hangs Firefox if a content policy is present

Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect)

Description

[Wladimir Palant]

Attachment: Minimal content policy for testing

This issue has been reported multiple times for Adblock Plus, it is Linux only. The page where it is reproducible without a valid login is the  online banking page of Danske Bank - reloading this page a few times with Adblock Plus installed always hangs Firefox. I reproduced it with Ubuntu from a live CD (this means Firefox 3.0.8 and Sun Java Plug-in 1.5.0_18-b02) with a minimal content policy component. The original reporter had Sun Java 6 and Firefox 3.0.10 on Ubuntu, could reproduce with Firefox 3.5b99 (official build) and Iceweasel on Debian Lenny as well however.

To reproduce: Download nsTestPolicy.js from the attachment and put it into /usr/lib/firefox-n.n.n/components directory (that's the directory path on Ubuntu, might be different for other distributions). Then create an ".autoreg" file in your Firefox profile. Then start Firefox and go to https://netbank.danskebank.dk/html/index.html?site=DBNB&secsystem=E2 (allow running the applet). Reload the page a few times, for me it always hanged up on third or forth reload.

[Daniel Veditz [:dveditz]]

probably not a 1.9.1 blocker given how close we are, but we should probably relnote it and fix it quickly after.

Comment 2

[Damon Sicore (:damons)]

I agree with Comment #1.  Additionally, since it's not a regression from 3, I'm going to minus this now.  If people disagree, please re-nom.

I just filed bug 501173 which might be caused by the same issue - but it has a simple Java applet as testcase.

Can we get this an owner?

Not going to block on this for .2, but can we get an owner for .3 or later? Dan things we should fix this soon, per comment 1.

Same crash (and 100% cpu) problem here.
[Firefox 3.5.1, Java 1.6.0_14, Crux Linux 2.5]

Comment 6 from bug 501173 did the trick.
