从IntelliJ运行JavaFX和Swing时的Segfault

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（build＃IC-145.258）

通过将javac运行到java该问题无法重现
通过oraclejdk（1.8.0_u77-b03）运行时也没有显示问题

作为参考，该计划的“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， 此要点的错误日志可在此要点获得。

我该如何解决这个问题？

Answer 1

可以在IntelliJ外部重现该错误，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 java -cp . Main在Ubuntu 15.10上

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

产生同样的致命错误。 而运行java -cp . Repo java -cp . Repo不会失败。

运行java -cp . Main java -cp . Main在CentOS 7上

openjdk版本“1.8.0_77”
OpenJDK运行时环境（版本1.8.0_77-b03）
OpenJDK 64位服务器VM（内置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版本以及调用类Repo的方式有关。

编辑如果您无法切换到另一个Java版本，则可能存在“解决方法”。 （根据这篇文章 ）

修改您的Repro.java如下所示，它不会在OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)上失败OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)

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