backtrace of epiphany crashing on site with java

I have installed libwebkit 1.2.0-1 and I had with three browsers using webkit (epiphany, arora, surf) the same problem: Whenever I entered a site using java the browser crashed. I have appended the console-output (and I have tried to compile e.g. epiphany with CFLAGS -g but could not get more detailed backtrace). Now I downgraded to openjdk6 6.b17_1.7.3-1 and everything seems to work fine again. Other browsers (e.g. conkeror, firefox, midori, ...) work fine. See http://bugs.archlinux.org/task/19273 for this error and fix.

Steps to reproduce:
install openjdk6 6.b18_1.8-1
install epiphany
browse e.g. www.klack.de
browser crashes

Im running Arch linux

This bug should be reassigned to the Gtk+ component. OpenJDK does work in Chrome, only browsers based on WebkitGTK+ are affected.

FWIW, this is terminal output from running an applet in Epiphany:

The browser UI freezes and pegs the CPU at this point.

WebKitGTK+ also crashes for me in the following URL:

Seems to be a problem with the timer being used after it got destroyed?

For me this hits the assertion:

INFO: Created user preferences directory.
ASSERTION FAILED: m_thread == currentThread()

[Martin Robinson]

Here's a bug which tracks that particular issue: https://bugs.webkit.org/show_bug.cgi?id=30814 I have have a suspicion that it is related to https://bugs.webkit.org/show_bug.cgi?id=32689 . I've pinged dimich about it.

[Sven Arvidsson]

With the new plugin, icedtea-web, Java applets seems to be working fine, at least in Epiphany 2.30.6.

[Martin Robinson]

Support for plugins was removed in https://trac.webkit.org/changeset/265753/webkit.
