World unload while Plugin3.0.0 is disabled.

[AKcel222]

Describe the issue
If I stop my Server i get an zip file closed error.

Spigot version
1.21.LATEST

Plugin version
3.0.0

How to reproduce
Unload method override on the paper ? I dont know
With this I mean that I saw a Unload Method on Paper or Spigot.
Which could get initiliazed with a Method that checks if the worlds are unloaded, then disable the plugin-3.0.0.jar.

I confirm, on my side it comes from MongoDB.

It's appear it comes from the new Class loader close method since bukkit 1.20.3
