Another Update
I made a new project, named it RavenLifeTools. Clean project, I made test environments for the server both on windows and linux (CentOS 9 Stream) and unix (FreeBSD). Both linux/unix systems give this error yet compiled the Class file. I decompiled the class file to see if any of my code got butchered. It was flawless.
It works perfect with no issues in a windows environment. If I compile the mod as a Jar it works flawless on both windows and *nix. Here is a screenshot of my console
here is my windows loading my source fine
and here is my dev environment
