        root.setTop(urlField);
        root.setCenter(webView);
        root.setBottom(goButton);

        Scene scene = new Scene(root, 800, 600);
        primaryStage.setScene(scene);
        primaryStage.setTitle("WebView Sample");
        primaryStage.show();
    }

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

CUSTOMER SUBMITTED WORKAROUND :
No, not for all examples. For google maps, javafx 18 is said to be working, but its also not working for the other two urls.   

FREQUENCY : always
