Description

Expected behavior

When changing the server-full message flag in spigot.yml, the message should display when the server is full and more players try to connect.

Observed/Actual behavior

The server always defaults to "The server is full!" regardless of what is typed in the config.

Steps/models to reproduce

Download a fresh Paper server jar
Agree to eula so server can run
Start server to populate default configs
Stop server
Edit server-full message in spigot.yml
Set player limit to 0 in server.properties
Start server
Connect to server
Observe that the message is not what you just typed

Plugin and Datapack List

None

Paper version

This server is running Paper version 1.21.8-58-main@9aaaadf (2025-09-03T22:14:30Z) (Implementing API version 1.21.8-R0.1-SNAPSHOT)
You are running the latest version

Other

I tested this with a fresh Spigot 1.21.8 jar install and it worked as expected.

Research direction

Reproduce the issue using spigot.yml and server.properties as described, then trace the server-full message handling from the connection attempt. Compare the Paper behavior with the reported working Spigot behavior. Done means the configured server-full message is displayed when the player limit prevents a connection.
