Forge 1.16.5 Server crashing while starting

[Ben_Rogers]

Hello everyone! I am very new to modded servers and have been running into an issue with my forge server. I am currently running MineOS on TrueNAS CORE. I have successfully gotten any vanilla version of minecraft to work without forge, but as soon as I use the forge .jar setting, the server always crashes. I have tried the following versions of java to try and fix this problem, openjdk8, openjdk8-jre, openjdk11, openjdk11-jre, openjdk15, and openjdk17. I have not attempted to load any mods yet, just forge. Here is the crash information I have received.

Thank you for your time!

So I know when I tried to start a forge server it did not work because of a bug with newer versions of certain Javas. Maybe this thread will help?

Forge server not starting

Hey I have been trying to start a forge server in 1.16.5 and it does not seem to want to start. I have selected the correct profiles but it just gives me error messages on startup. It will run on the normal 1.16.5 minecraft jar but not the forge one. If anyone has any advice or can understand the error messages that would be amazing. I have read a few other posts but I cannot find anything that works. I have tried java 17, java 11, and java 8 but none work. The jar I am trying to use is forge-1.…

However mine is uncaughtexception:1050 and yours is 1052. If it doesn’t work let me know. I hope that helps!
