Excuse me if I've misunderstood, but yes, I have the propriety nVidia drivers installed, which I suppose yes, do include OpenGL drivers.
All other applications the utilize the GPU work fine, including WebGL and native 3D games, so I think it's unlikely got anything to do with my drivers.
For whatever it's worth, I get the same error when I try and run the trial version of Spine with it's bundled JRE.
