Created attachment 54948 [details] 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 uname -a: Linux deskskunk 2.6.33-ARCH #1 SMP PREEMPT Mon Apr 26 20:00:20 CEST 2010 i686 AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ AuthenticAMD GNU/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: java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9pre) (6b20~pre1-2) OpenJDK Server VM (build 17.0-b16, mixed mode) /build/buildd-openjdk-6_6b20~pre1-2-i386-esIBaU/openjdk-6-6b20~pre1/build/../plugin/icedteanp/IcedTeaNPPlugin.cc:622: thread 0x873a750: Error: Unknown plugin value requested. java.lang.NullPointerException at sun.applet.PluginAppletViewer.handleMessage(PluginAppletViewer.java:649) at sun.applet.PluginStreamHandler.handleMessage(PluginStreamHandler.java:270) at sun.applet.PluginMessageHandlerWorker.run(PluginMessageHandlerWorker.java:82) java.lang.RuntimeException: Failed to handle message: width 170 height 150 for instance 1 at sun.applet.PluginAppletViewer.handleMessage(PluginAppletViewer.java:660) at sun.applet.PluginStreamHandler.handleMessage(PluginStreamHandler.java:270) at sun.applet.PluginMessageHandlerWorker.run(PluginMessageHandlerWorker.java:82) Caused by: java.lang.NullPointerException at sun.applet.PluginAppletViewer.handleMessage(PluginAppletViewer.java:649) ... 2 more The browser UI freezes and pegs the CPU at this point.
WebKitGTK+ also crashes for me in the following URL: ttps://www2.bancobrasil.com.br/aapf/login.jsp?aapf.IDH=sim&perfil=1 Program received signal SIGSEGV, Segmentation fault.

For me this hits the assertion: INFO: Created user preferences directory. ASSERTION FAILED: m_thread == currentThread()
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.
With the new plugin, icedtea-web, Java applets seems to be working fine, at least in Epiphany 2.30.6.
Support for plugins was removed in https://trac.webkit.org/changeset/265753/webkit.
