When using the "radial" css style for a paint, the runtime errors:

========= Foo.fx =============
import javafx.stage.Stage;
import javafx.scene.*;
import javafx.scene.paint.*;
import javafx.scene.shape.Circle;

public class Foo extends CustomNode {

    public var color: Paint = Color.BLACK;

    public override function create(): Node {
        Circle {
            centerX: 100,
            centerY: 100
            radius: 50
            fill: bind color
        };
    }
}

function run(args: String[] ) {
    Stage {
        title: "MyApp"
        scene: Scene {
            width: 200
            height: 200
            content: [
                Foo {
                    //style: "color: linear (0%,0%) to (100%,100%) stops (0.00,red),(1.00, blue);"
                    style: "color: radial (0%,0%),100% focus(25%,25%) stops (0.00,red),(1.00, blue);"
                }
            ]
        }
    }
