运行JavaFX时的分段故障和IntelliJ中的Swing

Question

在运行IntelliJ 2016.1社区版中的以下示例时，我总是遇到一个分段错误：

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();
    }
}

环境情况如下：

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

通过将javac运行到java中，这个问题是不可复制的。

当运行oraclejdk (1.8.0_u77b03)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和重新启动IntelliJ后，问题仍然存在

根据请求，此类执行的错误日志可在这个要点。上使用。

我怎样才能纠正这种行为呢？

Answer 1

此错误可以在IntelliJ外部按以下方式再现。

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

在Ubuntu15.10上运行java -cp . Main

openjdk版本“1.8.0_66-内部” OpenJDK运行时环境(Build1.8.0_66-内部-B17) OpenJDK 64位服务器VM (构建25.66-b17，混合模式)

会产生同样的致命错误。而运行java -cp . Repo并没有失败。

在CentOS 7上运行CentOS

openjdk版本"1.8.0_77“ OpenJDK运行时环境(Build1.8.0_77-b03) OpenJDK 64位服务器VM (build 25.77-b03，混合模式)

打开Swing JFrame和JavaFX窗格。

这个问题似乎与特定的OpenJDK版本以及类Repo的调用方式有关。

编辑如果你不能切换到另一个版本，就有一个可能的“解决办法”。(基于这个帖子)

修改您的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();
    ...
