Exception caught during firing event: Attempted to load class net/minecraft/client/Minecraft for invalid dist DEDICATED_SERVER

[EMilos4]

Hi, everyone and thanks for your attention.
My problem is that when I log in to my server it restarts, and in the console this comes out:

[19:56:04] [Server thread/WARN] [minecraft/MinecraftServer]: Can't keep up! Is the server overloaded? Running 4836ms or 96 ticks behind

[19:56:07] [Server thread/ERROR] [ne.mi.fm.lo.RuntimeDistCleaner/DISTXFORM]: Attempted to load class net/minecraft/client/Minecraft for invalid dist DEDICATED_SERVER

[19:56:07] [Server thread/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Exception caught during firing event: Attempted to load class net/minecraft/client/Minecraft for invalid dist DEDICATED_SERVER
