JavaFX应用程序在CentOS上死锁

标签： java javafx centos

我的JavaFX应用程序在Windows和Ubuntu下运行良好。 但是，在CentOS下，它一旦失去焦点就不会响应（例如，当我切换到另一个应用程序然后返回时）。一旦我用鼠标移动窗口，它也会冻结。

这种情况甚至发生在这个最小的JavaFX应用程序中：

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class SampleFX extends Application{
@Override
public void start(Stage primaryStage) throws Exception {
    Button btn = new Button("Click");
    btn.setOnAction(e -> btn_click());
    StackPane frame = new StackPane();
    frame.getChildren().add(btn);

    Scene scene = new Scene(frame, 200, 50);

    primaryStage.setScene(scene);
    primaryStage.setTitle("Hello World");
    primaryStage.show();
}
private void btn_click() {
    System.out.println("button was clicked");
}

public static void main (String[] args){
    launch(args);
}

}

Visual VM为我提供了以下threaddump：

似乎主要线程被锁定了...但是这样一个最小的应用程序中锁定的原因是什么？
