JNLPAppletLauncher is broken with u15.

Question

Running https://java3d.dev.java.net/applets/FourByFour.html twice after closing the browser crashes jnlpappletlauncher.
The first time it will run fine, but when getting the jars from the cache it crashes with an error:
JNLPAppletLauncher: static initializer
os.name = windows xp
nativePrefix = nativeSuffix = .dll
tmpRootDir = C:\DOCUME~1\Jim\LOCALS~1\Temp\jnlp-applet\jln8630845725920521382
Applet.init
subapplet.classname = org.jdesktop.j3d.examples.four_by_four.FourByFour
subapplet.displayname = Java 3D Four by Four Applet
Applet.start
os.name = windows xp
os.arch = x86

SEVERE: java.io.IOException: Cannot find certificates for JNLPAppletLauncher class
Trace level set to 5: all ... completed.
This is occurring because of this code:
       Certificate[] appletLauncherCerts = JNLPAppletLauncher.class.getProtectionDomain().
                getCodeSource().getCertificates();
        if (appletLauncherCerts == null || appletLauncherCerts.length == 0) {
            throw new IOException("Cannot find certificates for JNLPAppletLauncher class");
        }This was not the case for u14 and previous version of 1.6. Does anybody have a workaround/fix for the jnlpappletlauncher?

Hi Johnny. I'm trying to use your solution to get my applet working with u15.
My original Java 3d applet was:
<applet codebase="http://mmorpg.shattered.org"
code="org.jdesktop.applet.util.JNLPAppletLauncher"
width="200" height="160"
archive="

I changed it to:

but nothings happening. Wondering if you can see what I'm doing wrong.
