> ## Root Cause
> Animation gets started in a background thread, which causes the animation handler to run in the FX application thread, thus creating simultaneous access to the control's fields (list of children in this case).
> 
> ## Solution
> Postpone the animation unless running in the FX application thread.  There is no functional difference if the component is created/used in the FX application thread.
