title: java.lang.reflect.InvocationTargetException error javafx even though there is no code
body: <p>I am new to javafx so I decided to do a project,
  But when I run the program (literally no code inside the start method)
  It does not work it says java.lang.reflect.InvocationTargetException error and one more</p>
  <p>here is the code</p>
  <pre><code>
  package com.front.fire;
  
  import javafx.application.Application;
  import javafx.stage.Stage;
  
  class FrontFireMain extends Application{
  
      @Override
      public void start(Stage arg0) throws Exception {
          
      }
  
  }
  
  </code></pre>
