java - JCEF 与 JavaFX fatal error

Question

我正在尝试让 JCEF 在简单 JavaFX 应用程序的 swingNode 中工作

public class MainApp extends Application {

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

        SwingNode swingNode = new SwingNode();

        SwingUtilities.invokeAndWait(() -> {
            String startURL = "https://www.google.com/";
            boolean useOSR = OS.isLinux();
            boolean isTransparent = false;

            CefSettings settings = new CefSettings();
            settings.windowless_rendering_enabled = useOSR;

            CefApp cefApp_ = CefApp.getInstance(settings);
            CefClient client_ = cefApp_.createClient();
            CefBrowser browser_ = client_.createBrowser(startURL, useOSR, isTransparent);
            Component browerUI_ = browser_.getUIComponent();

            JPanel panel = new JPanel();
            panel.setSize(800, 600);
            panel.add(browerUI_, BorderLayout.CENTER);

            swingNode.setContent(panel);
        });

        stage.setScene(new Scene(new javafx.scene.Group(swingNode)));
        stage.show();
    }

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

我在 client_.createBrowser(startURL, useOSR, isTransparent); 处遇到 fatal error

但是，提供的 JCEF awt 测试示例可以完美运行。

JCEF Version = 3.2840.147
CEF Version = 3.2840.1511
Chromium Version = 54.0.2840.59
Oracle JDK version = 1.8.0_111

edit1:深入研究jcef java代码， fatal error 发生在CefBrowserOsr.java第134行

private void createGLCanvas() {
    GLProfile glprofile = GLProfile.getMaxFixedFunc(true); // here

edit2:错误日志hs_err_pid.log content .

Answer 1

升级到 JOGL 2.3.2 并再次重建 JCEF 部分解决了问题(不再发生 jvm 崩溃)

但是，似乎 SwingNode 不会渲染像 GLCanvas 这样非常复杂的东西，reference .
