I have build an applet with jogl 2.

It works fine with jnpl launch with Chrome, IE, and FireFox an Windows 32 bits and Windows post XP.

But With Safari on windows jnpl launch fails so i use JOGL Applet Launcher.
ON a first display of the page it works fine, but if you call the page later (without closing the navigator). The launch fail.

The bug also exist with the Demo applet :
http://jogamp.org/jogl-demos/www/applettest-jnlp.html
If you call a refresh of the page it works but if you call an other page and call the applet page next it fails.

The error from the applet viewer if the following :
Sorry its the full console output from the execution
