Thank you for your prompt response.
You may see: "-Dj3d.allowNullGraphicsConfig" in the jvm invocation,
/Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/bin/java -Dj3d.allowNullGraphicsConfig
 Is that right?
You write:
"Either GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice() is null in your configuration or GraphicsEnvironment.getLocalGraphicsEnvironment().
getDefaultScreenDevice().getBestConfiguration(GraphicsConfigTemplate) returns null"

Interestingly, neither assertion is bearing fruit. I shall attempt to print the references prior to the death of jvm so that you may see what I am seeing. First, the code:
public static void main(String[] args) {
        GraphicsEnvironment
                localGraphicsEnvironment
                = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice gd=localGraphicsEnvironment
                           .getDefaultScreenDevice();
        System.out.println
                ("GraphicsDevice" +
                 ":"+gd);
        GraphicsConfigTemplate3D
                template =  new GraphicsConfigTemplate3D();
//is this an OK way to create a template? Should I turn off some antialiasing features?
//or assert off-screen rendering?
        System.out.println
                ("template" +
                 ":"+template);
        //Here is where we kill the jvm:
        gd.getBestConfiguration(template);
    }
I hope I got the template code right....now for the output:

Is this some sort of awt error?
Sorry I am feeling really stuck here.

Thank you for your help!
