Where do you get the "Not on FX application thread" error? When trying to launch all those threads or when you try to update the GUI from within one of those threads? If it's the former, I can't help. If it's the latter, you simply need to run your update code on the UI thread. I don't use JavaFX but in my Java / Android, this works fine.

Java
// called from a fragment
Thread worker = new Thread (new Runnable ()
{
    @Override public void run ()
    {
        // stuff to do not on the UI thread
        // ...

        // stuff is done, time to tell the UI
        activity.runOnUiThread (new Runnable ()
        {
            @Override public void run ()
            {
                // code that touches the UI
            }
        });
    }
});
worker.start ();

Be wary of strong drink. It can make you shoot at tax collectors - and miss.
