Cannot create a new Browser using jxbrowser on linux - linux

Question

I have a small test program using jxbrowser working on a Mac. I am trying to run the test program on a Fedora install and I connot get an instance of a Browser object.
Here is the logging of the program. Does anyone have an idea of what can cause jxbrowser to fail creating the browser ?

Please make sure that your Linux environment isn't a headless environment. JxBrowser doesn't support headless linux environments without running X Server: https://jxbrowser.support.teamdev.com/support/solutions/articles/9000013733-system-requirements
