JOVR with JOGL and SDK rendering

I'm trying to get something really basic running with OSX, JOVR, OpenGL, JOGL, and SDK 0-4-1 rendering. But I'm getting this fatal error at step 5.5 in the code below.

    
        RenderAPIConfigHeader configHeader = new RenderAPIConfigHeader(resolution, 1);
        RenderAPIConfig apiConfig = new RenderAPIConfig(configHeader, new int[15]);

I don't know that this will work. I simply use the following:

These are not distortion caps. Distortion caps are of the type OvrLibrary.ovrDistortionCaps. I use the following:

        FovPort[] eyeFov = new FovPort[]{hmd.DefaultEyeFov[0], hmd.DefaultEyeFov[1]};

The commented out version is the correct one. Alternatively, you can simply pass in hmd.DefaultEyeFov.

        }

I'd suggest using the configureRendering() helper method on Hmd which encapsulates a number of parameter checks and allocates the output EyeRenderDesc parameters for you.

    RenderAPIConfig rc = new RenderAPIConfig();
    rc.Header.RTSize = hmd.Resolution;
    rc.Header.Multisample = 1;

    int distortionCaps = 
      ovrDistortionCap_Chromatic |
      ovrDistortionCap_TimeWarp |
      ovrDistortionCap_Vignette;

    eyeRenderDescs = hmd.configureRendering(
        rc, distortionCaps, hmd.DefaultEyeFov);

distortionCaps != hmdCaps.
