LOTS of errors: "Could not pass event ChunkUnloadEvent to WorldBorder v1.9.9 (beta)"

See original GitHub issue

First of all, I’m running a 1.14 server and I understand it’s not officially supported. Just figured I should post this error in the case you’re developing for 1.14.

Server version is spigot-1.14-R0.1-SNAPSHOT.jar:git-Spigot-1eece4f-0d76f86

When filling the world, I get thousands of instances of the following error:

> [06:58:43] [Server thread/INFO]: [WorldBorder] [Fill] 179 more chunks processed (7729 total, ~32.8%) (free mem: 3048 MB)

Same as above, that looks to be a core Spigot/Bukkit/NMS problem, no plugins are indicated in that crash log.

I thought so too, but it’s a crash that only started happening once I downgraded the plugin. I will take more steps to find a reliable way to reproduce it.

The stacktrace and crash log fully imply it’s Spigot/Bukkit/NMS, and (from past experience) that kind of error does show up almost every time a new major version release is dropped (1.12, 1.13, 1.14, etc.), so I’m 99% sure you’re wasting your time. But, if you feel like it, go for it.

Actually, after a quick google of that error, it’s a core NMS bug which Mojang have fixed in an upcoming NMS release:

So there you go. NMS bug, no fix available yet.

And for me… Exception generating new chunk
