title: JavaFX not available, what now?
body: <p>I have a JavaFX application, but when people try to run it nothing happens because they got no JavaFX on their system, because they are using OpenJDK for example.</p>
  
  <p>What can I do to inform people about the problem? </p>
  
  <p>Best way would be to have an Alert informing the user about that, is there a way to do this with basic Java functionality?</p>
