不更改任何代码而导致的异常

几天前,我为一个项目制作了这个javafx程序。今天,我打开了IntelliJ 2019.1,并运行了该应用程序,它没有明显的原因给我一个错误。

该程序运行良好,但是现在无需更改任何代码,它就有一个Exception。我查看了关于StackOverflow的问题,但没有一个回答我的问题。请不要将此标记为重复。

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

@Override
public void start(Stage stage) {
    stage.setTitle(TAG);

    GridPane gridPane = getGridPane();

    Scene scene = new Scene(gridPane);
    Setup setup = new Setup(buttons, scene, stage);
    setup.setup();
    stage.setScene(scene);
    stage.show();
}

private GridPane getGridPane() {
    GridPane gridPane = new GridPane();

    gridPane.setGridLinesVisible(true);
    gridPane.setPadding(new Insets(10));
    gridPane.setHgap(0);
    gridPane.setHgap(0);

    for (int i = 0; i < 9; i++)
        for (int j = 0; j < 9; j++) {
            buttons[i][j] = new Label("");
            buttons[i][j].setStyle("-fx-font-weight: bold; -fx-font-size: 40");
            buttons[i][j].setAlignment(Pos.CENTER);
            buttons[i][j].setTextAlignment(TextAlignment.CENTER);
            buttons[i][j].setMaxSize(Double.MAX_VALUE, Double.MAX_VALUE);
        }

    for (int i = 1; i <= 9; i++) {
        gridPane.getColumnConstraints().add(new ColumnConstraints(50));
        gridPane.getRowConstraints().add(new RowConstraints(50));
    }

    for (int i = 0; i < 9; i++) for (int j = 0; j < 9; j++) GridPane.setConstraints(buttons[i][j], j, i);

    for (int i = 0; i < 9; i++)
        for (int j = 0; j < 9; j++) gridPane.getChildren().add(buttons[i][j]);

    GridPane.setHalignment(gridPane, HPos.CENTER);
    GridPane.setValignment(gridPane, VPos.CENTER);
    gridPane.setAlignment(Pos.CENTER);

    return gridPane;
}

这是我的例外
