java - 从 IntelliJ 运行 JavaFX 和 Swing 时出现段错误

Question

从 IntelliJ 2016.1 社区版运行以下缩小示例时，我总是遇到段错误:

import javax.swing.*;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class Repro extends Application {

    public static void main(String[] args) {
        JFrame swingFrame = new JFrame();
        swingFrame.setTitle("Repro start");
        swingFrame.setSize(200, 350);
        swingFrame.setVisible(true);

        Application.launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        Pane root = new Pane();
        root.setMinHeight(200);
        root.setMinWidth(350);
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.show();
    }
}

环境如下:

• Ubuntu 15.10
• openjdk-8(1.8.0_u66 构建 17)
• openjfx-8 (8u60-b27-4)
• IntelliJ 2016.1 社区版(build #IC-145.258)

在 java
中运行 javac 无法重现该问题通过oraclejdk(1.8.0_u77-b03)运行也没有显示问题

作为引用，程序的“输出”如下:

运行 ulimit -c unlimited 并重新启动 IntelliJ 后问题仍然存在

根据要求，此类执行的错误日志可在 this gist. 获得。

我该如何解决这个问题？

Answer 1

错误可以在 IntelliJ 之外重现，如下所示。

public class Main {
    public static void main(String[] args) throws Exception {
        new Repro().main(new String[0]);
    }
}

运行 java -cp 。 Main 在 Ubuntu 15.10 上有

openjdk version "1.8.0_66-internal"
OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)
OpenJDK 64-Bit Server VM (build 25.66-b17, mixed mode)

产生相同的 fatal error 。而运行 java -cp 。 repo 不会失败。

运行 java -cp 。 CentOS 7 上的主

openjdk version "1.8.0_77"
OpenJDK Runtime Environment (build 1.8.0_77-b03)
OpenJDK 64-Bit Server VM (build 25.77-b03, mixed mode)

打开 Swing JFrame 和 JavaFX Pane 。

似乎这个问题与特定的 OpenJDK 版本和类 Repo 的调用方式有关。

编辑 如果您不能切换到另一个 Java 版本，则有一个可能的“解决方法”。 (基于此 post )

修改你的 Repro.java 如下，它不会在 OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)

上失败

public static void main(String[] args) throws Exception {
    new JFXPanel(); // the "workaround" to initialize the toolkit
    JFrame swingFrame = new JFrame();
    ...
