JavaFX文本字段导致编译错误

Question

我已经开始为一个个人项目学习JavaFX，事情进展顺利，直到我遇到了创建一组文本字段的问题。据我所知，代码是正确的，我使用的IDE没有给出任何错误指示。但当我尝试运行程序时，它会抛出一长串错误，这些错误在我注释创建文本字段的代码时不会发生。当这些代码行被省略时，程序将完全按照它应该的方式运行。

我正在使用InteliJ Idea，Windows 10，Javafx SDK 14.0.1和Java JDK 14.0.1

我在下面包含了我正在使用的代码。这个程序非常简单，所以我把它全部包括进来，以防我之前忽略了一些东西。

package library.test;

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.shape.*;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class main extends Application {

@Override
public void start(Stage primaryStage) {

    // Create the grid plane
    GridPane pane =new GridPane();
    pane.setHgap(10);
    pane.setVgap(6);
    pane.setAlignment(Pos.TOP_CENTER);

    // Create the scene
    Scene scene=new Scene(pane,500,500);
    primaryStage.setScene(scene);
    primaryStage.setTitle("Book Catalog");
    primaryStage.show();

    // Create the elements for the table
    Text tTitle = new Text("Title");
    Text tAuthor = new Text("Author");
    Text tGenre = new Text("Genre");
    Text tFormat = new Text("Format");
    Text tISBN = new Text("ISBN");

    TextField fTitle=new TextField();
    TextField fAuthor=new TextField();
    TextField fGenre=new TextField();
    TextField fFormat=new TextField();
    TextField fISBN =new TextField();

    // Add the elements of the scene
    pane.add(tTitle,1,1);
    pane.add(tAuthor,3,1);
    pane.add(tGenre,5,1);
    pane.add(tFormat,7,1);
    pane.add(tISBN,8,1);

    pane.add(fTitle,2,3);

}

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

我对编程这方面非常陌生，所以如果我错过了一些明显的东西，我道歉。提前谢谢！

多亏了@Slaw的帮助，我才得以解决这个问题。在文章JavaFX 11: IllegalAccessError当创建标签时，表明这只是一个VM选项问题。一旦我输入了前面提到的链接中显示的适当的路径选项和参数，我的代码就完全按照预期工作了。

再次感谢@Slaw的帮助！抱歉这么久才回复。我真的以为我已经做了。
