javaFX Application launch error

I'm new to working with javaFX and recently ran into the following error when running the application through Eclipse. My code:

import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class WindowBetaV02 extends AbstractWindow{

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

    public void start(Stage mainStage){
        height = 480;
        width = 640;
        mainStage = new Stage();
        mainStage.setTitle("AMQ");
        mainStage.setScene(drawGUIGameNormal());
        mainStage.setResizable(false);
        mainStage.show();
    }

    private Scene drawGUIGameNormal(){
        //Draw gui
    }
}

import javafx.application.Application;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.RowConstraints;
import javafx.stage.Stage;

public abstract class AbstractWindow extends Application {
    protected int height;
    protected int width;
    protected GameFunctions controller;

    public abstract void start(Stage stage);

    protected GridPane createPlayerPane(int width, int height){
        GridPane playerPane = createPixelGridPane(width, height);
        playerPane.getStyleClass().add("playerPane");       
        playerPane.add(createPlayerTable(), 10, 10, width-10, width-10);
        return playerPane;
    }

    @SuppressWarnings({ "rawtypes", "unchecked" })
    protected TableView createPlayerTable(){
        TableView table = new TableView();
        TableColumn points = new TableColumn("Points");
        points.setMaxWidth(30);
        points.setMinWidth(30);
        points.setCellFactory(new PropertyValueFactory<Players, Integer>("points"));

        TableColumn player = new TableColumn("Player");
        player.setMaxWidth(100);
        player.setMinWidth(100);
        player.setCellFactory(new PropertyValueFactory<Players, String>("playerName")); 

        table.setItems(controller.getPlayers());
        table.getColumns().addAll(player, points);

        return table;
    }

    protected GridPane createPixelGridPane(int width, int height){
        GridPane pane = new GridPane();
        for(int i = 0; i < width; i++){
            pane.getColumnConstraints().add(new ColumnConstraints(1));
        }
        for(int i = 0; i < height; i++){
            pane.getRowConstraints().add(new RowConstraints(1));
        }
        return pane;
    }
}

The error

Anyone know how to fix this error?

-Edit-

Added the code for the AbstractWindow class
