JOGL in macOS : can't get a program to compile and execute

Question

I'm trying to compile and execute a program I found here:

https://github.com/nekonaute/WorldOfCells

It works fine on Linux (with linux-amd64), but on my own MacBook Pro (with Intel Core i5), I'm running into issues. I'm trying a few approaches both on my Mac and on an Ubuntu virtual machine. I'd appreciate it if anyone could point me in the right direction because I'm starting to spin my wheels.

First the Mac, which seems promising because it compiles at least :

Pauls-MacBook-Pro:WorldOfCells pauljarski$ javac -classpath "./jogl/gluegen2-rt.jar:./jogl/jogl2.jar:." applications/simpleworld/*.java
Picked up _JAVA_OPTIONS: -Djogl.disable.openglcore
Pauls-MacBook-Pro:WorldOfCells pauljarski$ java -classpath "./jogl/gluegen2-rt.jar:./jogl/jogl2.jar:." applications/simpleworld/MyEcosystem 
Picked up _JAVA_OPTIONS: -Djogl.disable.openglcore
Landscape contains 40000 tiles. (200x200)

Unfortunately gluegen2-rt doesn't seem to exist anywhere. I created that macosx-universal folder and filled it with everything that seemed pertinent. No luck though.

On the virtual machine it also compiled, but...

Thanks in advance for your help!
