title: javaFX Application launch error
body: <p>I'm new to working with javaFX and recently ran into the following error when running the application through Eclipse.
  My code:</p>
  
  <pre><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
      }
  }

  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;
      }

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