I made a PR to fix this:

https://github.com/hharrison/java3d-core/pull/24

I hope you find it useful.
It works with my fork of sweethome3d (https://github.com/bigianb/refactoredHome3D) but I've not tested it any further as getting the 3D window of sh3d to work on my laptop was the sole motivator of this.
