從IntelliJ運行JavaFX和Swing時的Segfault

Question

從IntelliJ 2016.1社區版運行以下縮小示例時，我總是遇到分段錯誤：

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();
    }
}

環境如下：

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

通過將javac運行到java該問題無法重現
通過oraclejdk（1.8.0_u77-b03）運行時也沒有顯示問題

作為參考，該計划的“輸出”如下：

運行ulimit -c unlimited並重新啟動IntelliJ后問題仍然存在

根據要求， 此要點的錯誤日志可在此要點獲得。

我該如何解決這個問題？

Answer 1

可以在IntelliJ外部重現該錯誤，如下所示。

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

運行java -cp . Main java -cp . Main在Ubuntu 15.10上

openjdk版“1.8.0_66-internal”
OpenJDK運行時環境（build 1.8.0_66-internal-b17）
OpenJDK 64位服務器VM（內置25.66-b17，混合模式）

產生同樣的致命錯誤。 而運行java -cp . Repo java -cp . Repo不會失敗。

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

openjdk版本“1.8.0_77”
OpenJDK運行時環境（版本1.8.0_77-b03）
OpenJDK 64位服務器VM（內置25.77-b03，混合模式）

打開Swing JFrame和JavaFX窗格。

似乎這個問題與特定的OpenJDK版本以及調用類Repo的方式有關。

編輯如果您無法切換到另一個Java版本，則可能存在“解決方法”。 （根據這篇文章 ）

修改您的Repro.java如下所示，它不會在OpenJDK Runtime Environment (build 1.8.0_66-internal-b17)上失敗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();
    ...
