Some simple code to reproduce the Exception:

public class TextBoxException extends Application {
  public static void main(String[] args) {
    Launcher.launch(TextBoxException.class, args);
  }

  @Override
  public void start(Stage primaryStage) {
    TextBox name = new TextBox();
    name.setText("Name");
    primaryStage.setScene(new Scene(name, 500, 500));
    primaryStage.setTitle("TextBox Exception");
    primaryStage.setVisible(true);
  }
}
