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，我总是遇到分段错误：

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 build 17)
• openjfx-8 (8u60-b27-4)
• IntelliJ 2016.1 社区版（内部版本 #IC-145.258）

将javac 运行到java 中无法重现该问题
通过oraclejdk（1.8.0_u77-b03）运行时也没有显示该问题

作为参考，程序的“输出”如下：

运行ulimit -c unlimited并重启IntelliJ后问题依旧

根据要求，可在this gist. 获得此类执行的错误日志

如何解决此问题？

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]);
    }
}

在 Ubuntu 15.10 上运行 java -cp . Main

openjdk 版本“1.8.0_66-internal”
OpenJDK 运行时环境（内部版本 1.8.0_66-internal-b17）
OpenJDK 64 位服务器 VM（内部版本 25.66-b17，混合模式）

产生相同的致命错误。而运行java -cp . Repo 不会失败。

在 CentOS 7 上运行 java -cp . Main

openjdk 版本“1.8.0_77”
OpenJDK 运行时环境（内部版本 1.8.0_77-b03）
OpenJDK 64 位服务器 VM（内部版本 25.77-b03，混合模式）

打开 Swing JFrame 和 JavaFX 窗格。

似乎这个问题与特定的 OpenJDK 版本以及类 Repo 的调用方式有关。

edit 如果您无法切换到另一个 Java 版本，则可能存在“解决方法”。 （基于此post）

如下修改你的Repro.java，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();
    ...
