I get the same exception under somewhat different circumstances.
I am converting from a Java Web Start application to a desktop application. The Web Start application works fine! I extracted all the jar files from the Web Start download libraries and packaged them in my install program, which installs my program nicely. On the command line, the desktop application gives me the stack trace:
dyn-25-251:PathwayEditorWebIndependent workbenchdev$ java -classpath . -jar PathwayEditorWebIndependent.jar

All the jnilib files were extracted from the May 22, 2008 releases of jar files contained in
http://download.java.net/media/jogl/builds/archive/jsr-231-webstart-current/FYI, the classpath in the manifest file in the PathwayEditorWebIndependent.jar file is:
Class-Path: . jogl.dll jogl_awt.dll jogl_cg.dll jogl.jar gluegen-rt.jar libgluegen-rt.jnilib libjogl.jnilib libjogl_awt.jnilib libjogl_cg.jnilib
(The installer program works on both Windows and Mac OS X)
The main window for the application displays as it should, but I can't draw on the display panel.
