1.11.2 Minecraft server crashes when player tries to join/ping server
问题
我正在尝试在本地机器上设置一个1.11.2版本的Minecraft服务器，但每当玩家尝试加入或ping服务器时，它都会崩溃。我还注意到，当它启动时，会出现一些我以前从未见过并且不太理解的警告。

I'm trying to set up a 1.11.2 Minecraft server on a local machine, but it crashes every time a player tries to join or ping the server. I've also noticed that when it starts, there are a couple of warnings that I've never seen before and don't really understand

This is the error when a player tries to join:
