Chaining Lighting to Reflection produces NullPointerException. This is a problem in 8u40 b20, but not an issue in 8u25 and earlier. Here is a sample program that can be used to reproduce exception.

{code}
import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.scene.Group;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.effect.Lighting;
import javafx.scene.effect.Reflection;
import javafx.scene.layout.HBox;
import javafx.scene.text.Text;
import javafx.stage.Stage;


public class HelloFX extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        stage.show();

        Scene scene = new Scene(new Group(), 400, 400);
        ObservableList<Node> content = ((Group) scene.getRoot()).getChildren();

        content.add(chainEffects());
        stage.setScene(scene);

    }

    static Node chainEffects() {

        Text text1 = new Text("Hello");
        text1.setStyle("-fx-font-size: 100pt");

        Lighting lighting = new Lighting();

        Reflection reflection = new Reflection();
        reflection.setInput(lighting);

        HBox hbox = new HBox();
        hbox.getChildren().add(text1);
        hbox.setEffect(reflection);

        return hbox;
    }

    public static void main(String[] args) {
        Application.launch(args);
    }
}
{code}
