IcedTea6-plugin PluginAppletSecurityContext NullPointers

[Oliver May]

Hi all!

I am having some difficulties with icedtea-6-plugin on debian (armel). I 
am working on a java applet for communication between a browser 
(iceweasel) and hardware (gpsd) on the neo freerunner phone.

The problem lies mainly in the communication between the browser and the 
applet, I am calling java methods from javascript code. Whenever I try 
to call a method on a java object I get following errors:

java.lang.NullPointerException:
	at 
sun.applet.PluginAppletSecurityContext.checkPermission(PluginAppletSecurityContext.java:1002)
	at 
sun.applet.PluginAppletSecurityContext.handleMessage(PluginAppletSecurityContext.java:658)
	at 
sun.applet.AppletSecurityContextManager.handleMessage(AppletSecurityContextManager.java:31)
	at 
sun.applet.PluginStreamHandler.handleMessage(PluginStreamHandler.java:248)
	at 
sun.applet.PluginMessageHandlerWorker.run(PluginMessageHandlerWorker.java:34)

Occasionally I also get following error:
IcedTeaPlugin.cc:4735: Error: parse int


My configuration:

Icedtea6-plugin: Version: 6b14-1~exp1
Openjdk6-jre: Version: 6b14-1~exp1
Iceweasel: 3.06-1
Linux debian-gta02 2.6.24-20081103.git7172ec57 #1 PREEMPT Wed Dec 17 
18:06:43 UTC 2008 armv4tl GNU/Linux

I have also set up a x86 debian installation in a virtual machine with 
the same package configuration as on the phone. And the same errors 
occur there, so i guess it's not platform (armel) related.


kind regards,
