A DESCRIPTION OF THE PROBLEM :
Our JavaFX application constantly crashes on one customers Mac computer under his account. Hiwever, it works fine on a lot of other computers.

This customer has installed a lot of add-ons and replacement software for his computer. The problem may origin from there. However, the JVM should not crash anyway.

The application starts fine, but when the user selects a specific layout the application crashes.

I suspect that the bug gets caused by some specific layout or CSS.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the application on this customers computer, and select the proplematic layout (a button which changes things in the view)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The application should not crash
ACTUAL -
The Application crashes

REPRODUCIBILITY :
This bug can be reproduced always.
