问题 I have a program that uses a simple preloader while the init() method creates the main gui. Everything works fine but after the init() method completes and the preloader disappears, there's a noticeable delay before the main stage shows up. I say noticeable because it can be as much as 7 seconds, enough for a user to get confused.

问题 for example: public class WebViewTest extends Application { @Override public void start(Stage primaryStage) throws Exception { final WebView view = new WebView(); final WebEngine webEngine = view.getEngine(); Scene scene = new Scene(view, 600, 600); primaryStage.setScene(scene); primaryStage.show(); Platform.runLater(() -> { webEngine.getLoadWorker().progressProperty().addListener(new ChangeListener<Number>() { @Override public void changed(ObservableValue<? extends Number> observable, Number
