I am not so familiar w/ Java3D, are these caps related to GLCapabilities ?
If so, you can always query all GLCapabilities for a specific device
w/o the need to create a dummy window. This is b/c we do query them
at JOGL initialization, which didn't exist in JOGL1.

<http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLDrawableFactory.html#getAvailableCapabilities%28javax.media.nativewindow.AbstractGraphicsDevice%29>

Further more, one can also query available GLProfiles for one device:

<http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLProfile.html#getMaxProgrammableCore%28javax.media.nativewindow.AbstractGraphicsDevice,%20boolean%29>
.. etc ..
