Minor Hello. Instead of:
com.mojang.authlib.GameProfile@55ba7da0[id=3a4bc2f1-5e77-3e23-ba29-ae631e4c611a,name=My Player Name,properties={},legacy=false] (/127.0.0.1:50000) ...
It would be better to display only the name of player:
My Player Name (/127.0.0.1:50000) ...
These messages during server work appears quite a lot and server log fills up. In the result, find something important becomes problematic (IP's was changed)..
