and
IcedTea-Web Plugin (using IcedTea-Web 1.2 (1.2-2ubuntu1.2))


#first install the icedtea-7-plugin
apt-get install icedtea-7-plugin

# next configure firefox to use the icedtea-7-plugin

The applets loads fine using JamVM and Hotspot.

Thanks for the report, but I'm not able to reproduce this one. Have you
tried removing your ~/.icedtea directory in case there's something
corrupted in your cache?

Here's the output I get:

jdubuntu120432: DISPLAY=:0 firefox http://oneslime.net

java version "1.7.0_07"

Avian (build 0.6, )

One Slime: http://oneslime.net/

The applet seems to load fine, and I only get further output when I close
the browser:

Thanks for the report, but I'm not able to reproduce this one.  Have you
tried removing your ~/.icedtea directory in case there's something
corrupted in your cache?

Here's the output I get:

Avian from the latest Ubuntu deb runs the applets fine now after removing .icedtea folder.
I think you are spot on about something corrupt in the icedtea cache:
New output:

The applet seems to load fine, and I only get further output when I close
the browser:

java/security/AccessControlException: Applets may not call System.exit()
   at net/sourceforge/jnlp/runtime/JNLPSecurityManager.checkExit (line 385)
   at java/lang/Runtime.exit (line 105)

   at sun/applet/PluginStreamHandler.access$000 (line 52)
   at sun/applet/PluginStreamHandler$1.run (line 92)

This exception sounds OK. And a reasonable exception to see if the applet tries to use System.exit();
All fine.
