Using JRE 8 and JDK 8 on OSX High Sierra for Minecraft 1.10.2

Please post your entire fml-server-latest.log file in spoiler tags (the little eyeball button above where you type your post), or upload it to somewhere like gist.github.com and link to it here.

There is no server log in the folder or log folder, this is what I get when i use my start.command for my universal forge file. The logs do show however if I just launch the minecraft_server.1.10.2.jar

That. . .is very weird.

I'm at a loss, unless your java's broken and needs to be reinstalled. I really am not sure without having logs to go by.
