Steps/models to reproduce

Call some methods in Bukkit.getConsoleSender() in a plugin's onEnable(). After this, running any unknown command will print this error instead of "Unknown command message". More testing is needed as for which methods in the sender actually break this.

This started to happen in an unknown Paper update, unfortunately I don't have the time to pinpoint to the exact build.

For some reason now I am getting this. Unfortunately I am not able to pinpoint the exact cause:

That error doesn't seem possible. It can't find the service via java's service loader API. Is something messing with the META-INF in the server or something removing it?
