title: JavaFx execution can not finish until the stop method of the Application class has not returned?
body: <p>I learned that the stop method of the Application class of the
  JavaFX application is called when it is about to terminate.
  Does it mean that all the threads of my application continues to execute until the stop method has not returned?</p>
  
  <p>So the termination of my application’s threads start meanwhile the execution of the stop method, or the termination of the threads start only after the stop method finished execution?</p>
