我试图在netbeans和场景构建器中使用javafx为学校项目创建UI，但是当我尝试运行该程序时，它在Application start方法中显示异常，有人可以解决该问题吗？

这是fxml代码     

<?import com.jfoenix.controls.JFXButton?>
<?import com.jfoenix.controls.JFXPasswordField?>
<?import com.jfoenix.controls.JFXTextField?>
<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIcon?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.image.Image?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.Pane?>
<?import javafx.scene.text.Font?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="451.0" prefWidth="754.0" style="-fx-background-color: #20120f;" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/11.0.1" fx:controller="chatapp.FXMLDocumentController">
  <children>
  <ImageView fitHeight="451.0" fitWidth="754.0" opacity="0.51" pickOnBounds="true">
     <image>
        <Image url="@../images/arctic_wolf_winter_mountains_5k.jpg" />
     </image>
  </ImageView>
  <AnchorPane layoutX="416.0" layoutY="50.0" prefHeight="377.0" prefWidth="300.0" style="-fx-background-color: #9c2827;">
     <children>
        <JFXTextField focusColor="#030e75" labelFloat="true" layoutX="37.0" layoutY="90.0" prefHeight="25.0" prefWidth="227.0" promptText="Username/Email" unFocusColor="WHITE">
           <font>
              <Font size="14.0" />
           </font>
        </JFXTextField>
        <JFXPasswordField focusColor="#030e75" labelFloat="true" layoutX="37.0" layoutY="156.0" prefHeight="25.0" prefWidth="227.0" promptText="password" unFocusColor="WHITE">
           <font>
              <Font size="14.0" />
           </font>
        </JFXPasswordField>
        <JFXButton layoutX="37.0" layoutY="238.0" prefHeight="29.0" prefWidth="227.0" style="-fx-background-color: #e45652;" text="Sign In" textFill="WHITE" />
        <Label layoutX="121.0" layoutY="29.0" prefHeight="34.0" prefWidth="79.0" text="Sign In" textFill="#f2f2f2">
           <font>
              <Font size="24.0" />
           </font>
        </Label>
        <Label layoutX="111.0" layoutY="305.0" text="Forgot Password?" textFill="#eee8e8" underline="true">
           <font>
              <Font name="Times New Roman" size="13.0" />
           </font>
        </Label>
     </children>
  </AnchorPane>
  <Label layoutX="32.0" layoutY="136.0" text="Welcome to Chatbox" textFill="#f2eeee">
     <font>
        <Font name="System Bold" size="36.0" />
     </font>
  </Label>
  <Label layoutX="47.0" layoutY="205.0" text="A messenger app unlike any!!! Stay connected with your &#10;friends and loved ones through multiple social networks" textAlignment="JUSTIFY" textFill="#fff8f8" />
  <JFXButton layoutX="120.0" layoutY="249.0" prefHeight="29.0" prefWidth="180.0" style="-fx-background-color: #e45652;" text="Sign up" textFill="WHITE" />
  <Pane layoutX="611.0" layoutY="1.0" onMouseClicked="#handleclose" prefHeight="34.0" prefWidth="142.0">
     <children>
        <FontAwesomeIcon fill="#fcf8f8" iconName="CLOSE" layoutX="109.0" layoutY="22.0" onMouseClicked="#handleclose" size="1.5em" />
     </children>
  </Pane>
 </children>
</AnchorPane>

这是控制器

package chatapp;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;

public class FXMLDocumentController implements Initializable {

    @FXML
    private Label label;

    @FXML

    private void handleclose(ActionEvent event) {
       System.exit(0);
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {
    // TODO
    }    

   }

这是主要方法

package chatapp;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

public class Chatapp extends Application {

@Override
public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
    stage.initStyle(StageStyle.UNDECORATED);
    Scene scene = new Scene(root);

    stage.setScene(scene);
    stage.show();
}

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

}

最后这是控制台中显示的错误
