Issue Launching Modded Server


Recommended Posts

Trying to get a server set up for a moderately-sized group of people, but encountering significant resistance where I've never really had an issue with forge modding before. It's a sizeable modlist, but I found when testing even just 2 mods, the whole thing crashes.

Mod List:



Debug Log (With these mods)

Debug Log (Just 2 mods)

Of note, EVERYTHING works in singleplayer, so I'm not sure why this issue is server-specific

[23Sep2022 08:46:46.323] [main/WARN] [mixin/]: Error loading class: java/util/Optional (java.lang.IllegalArgumentException: Unsupported class file major version 63)

Mixin doesn't like that you are using java 19 which was only released last week. 🙂 

Use java 17 which is the current LTS (long term support) version.



If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
