TuioFX vs Animation

[AldoSilvaLuna]

Hi, first of all thank you for the great work you've done. I've been trying to use TuioFX to make a school project running on xUbuntu 16.04 with Java 8.

I managed to find 2 kinds of bugs.

The problem is that when I touch the screen the console just keeps printing non stop Exception A. Exception B just occurs a couple of times.

This 2 bugs don't always occur, only when you touch the screen repeatedly multiple times with multiple points. I hope you guys can help me, thank you.
