[1.20.1] Crashing not able to find class file.

[MrBloom2037]

Minecraft Version : 1.20.1

Mohist Version : 1.20.1-775

Operating System : Windows 11 (amd64) version 10.0

JVM Version: 21.0.2

Concerned mod / plugin : JEG 0.5.3 | JustEnoughGuns | https://www.curseforge.com/minecraft/mc-mods/just-enough-guns

Logs : https://pastebin.com/wquP8YY7

Steps to Reproduce :

1. Add mod to mods folder
2. Start server, server gets to mod initialization.
3. Server crashes due to the server unable to find the class even though the class file is present.

Description of issue : java.lang.NoClassDefFoundError: ttv/migami/jeg/item/AnimatedGunItem is specific to the class but isn't specific as to why it cannot load the mods class file though its present in the jar file.

Use java17 for testing, don't use java21

I'll build a version of Mohist standalone to run using JDK 17, I'm unsure its the JVM build thats causing it though.

Recent crash report with JVM 17.0.11
This is with the mod by itself in the mods directory.

After testing, you need to install geckolib mod to run

really wow, thank you for letting me know I'll run a test on my experimental server to see if this fixes it.

Your fix was absolutely on point even the mod developer pointed out that, glad for your help it didn't show that the mod was missing in the stacktrace I had so I am shocked you were able to find it.
