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）

将javac运行到java中，无法重现此问题通过oraclejdk（1.8.0_u77-b03）

运行时，问题也没有显示出来

作为参考，该程序的“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，this gist.

提供了此类执行的错误日志

如何解决此问题？

Answer 1

错误可以在IntelliJ之外复制，如下所示。

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

使用

在Ubuntu 15.10上运行java -cp . Main

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

会产生同样的致命错误。而java -cp . Repo运行不会失败。

使用

在CentOS 7上运行java -cp . Main

openjdk version“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其他Java版本，则可能存在“解决方法”。（基于此post）

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

不会失败

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

从IntelliJ运行JavaFX和Swing时的Segfault
