Access restriction: The constructor GraphicsConfigTemplate3D() is not accessible due to restriction on required library /System/Library/Java/Extensions/j3dcore.jar

This problem is reported by Eclipse. It's reason why project can't by compiled.

Problem is that default JRE include older 1.5 Java3D implementation which doesn't expose used GraphicsConfigTemplate3D() constructor. Solution is remove from eclipse build old 1.5 Java3D libraries and and new 1.6 to class paths.

How to configure it in eclipse is described it post Mac OS X 10.9 Mavericks how to install Java 3d.
