Running javafx cross-platform .jar on ubuntu

Question

I created cross-platform .jar file with maven shade plugin. This jar works fine on windows, but when I try to run it on ubuntu I get an Exception:

I have installed gtk:

sudo apt-get install libgtk-3-dev

...and openjfx:

sudo apt-get install openjfx

...but it didn't help.

Is this problem with my .jar, or I need to do smth with my ubuntu jdk configuration? How can I solve this problem? Thanks for any help.
