Tests :

• I've try to remove the config but it doesn't work.

• Another test that we have done, is to delete all files of cartographer2 but the error still happend at the start of the server.

• On paper #133, we hadn't this behaviour.

Versions used : Cartographer2 (Cartographer2 v2.12.16) Waypoints (1.5) Paper (#143)

Which version of Java are you using?

Hi @BananaPuncher714

We using openjdk-11 under our own docker image (builded FROM openjdk:11 image) : https://hub.docker.com/repository/docker/nefald/papermc

• I updated to Paper #146, the error still occurred.
• I runned the server just with Cartographer2, the error still occurred.

Details

• Openjdk-11
• Cartographer2 2.12.16
• Waypoints 1.5
• Paper 1.15.2 #146

Thanks !

This appears to be an issue with compiling Paper on Java 11 and TinyProtocol being unable to locate the correct classes. I'll see what I can do.

[BananaPuncher714]

The newest version (2.12.17) should fix these problems. Re-open this issue if the errors still persist.

Thanks @BananaPuncher714 ! :)
