Question

在下面的示例中，如果用户填写密码并按Enter键，则应用程序崩溃。这种情况发生在大约50％的时间。如果用户使用鼠标按下OK按钮，一切都按预期工作。在Suse Linux上可以看到这种行为。

是否有人有针对此行为的解决方法的提示？

转载于以下平台：

SUSE 13.2
SUSE 42.2
SUSE Tumbleweed

我在Windows或Mac上看不到这种行为。

JDK转载于：

Oracle jdk1.8.0_121
Oracle jdk1.8.0_131
Oracle jdk1.8.0_144

我无法在java 9上的预发行版中重现这一点。

import javafx.application.Application;
import javafx.scene.control.ButtonType;
import javafx.scene.control.Dialog;
import javafx.scene.control.PasswordField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;


public class PasswordDialogCrash extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        PasswordField passwordPasswordField = new PasswordField();
        GridPane grid = new GridPane();
        grid.add(passwordPasswordField, 1, 2);
        passwordPasswordField.setFocusTraversable(true);

        Dialog<String> dialog = new Dialog<>();
        dialog.getDialogPane().getButtonTypes().addAll(ButtonType.OK,  ButtonType.CLOSE);
        dialog.getDialogPane().setContent(grid);
        dialog.showAndWait();
        System.out.println("Done");
    }
}

结果：
