javafx - JxBrowser 无法在 JavaFX 中配置

Question

我使用 Tabpane 多个浏览器；当我关闭一个选项卡时，我无法处理主 IPC:

public class JxbrowserDemo extends Application {
    @Override
    public void start(Stage primaryStage) {
        setLevel(Level.ALL);
        TabPane tabPane = new TabPane();
        tabPane.getTabs().add(createBrowserTab());
        tabPane.getTabs().add(createBrowserTab());
        StackPane pane = new StackPane();
        pane.getChildren().add(tabPane);
        Scene scene = new Scene(pane, 500, 400);
        primaryStage.setTitle("JxBrowser: JavaFX - Hello World");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public Tab createBrowserTab() {
        Tab tab = new Tab("baidu");
        Browser browser = new Browser();
        BrowserView browserView = new BrowserView(browser);

        tab.setOnClosed(new EventHandler<Event>() {
            @Override
            public void handle(Event event) {
                //last tag close throw exception
                //
                browser.dispose();
            }
        });

        tab.setContent(browserView);
        browser.loadURL("www.google.com");
        //tabPane.getTabs().add(tab);
        //browserArrayList.add(browser);
        return tab;
    }

    @Override
    public void stop() throws Exception {
        //dispose here Success
        /*browserArrayList.forEach(t->{
            t.dispose();
        });*/
        super.stop();
    }

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

在这里挂断。

大约五分钟后它抛出异常:

尝试在非 JavaFx 应用程序线程中处理浏览器实例:

        tab.setOnClosed(new EventHandler<Event>() {
        @Override
        public void handle(Event event) {
            //last tag close throw exception
            //
            new Thread(new Runnable() {
                @Override
                public void run() {
                    browser.dispose();
                }
            }).start();
        }
    });
