Description

MythicMobs doesn't work and gives me the error java.lang.NoSuchMethodError: 'void org.bukkit.inventory.meta.ItemMeta.displayName(net.kyori.adventure.text.Component)'. It worked fine with Paper and Spigot, so this is a problem caused by Arclight.

Step to reproduce

1. Download the latest version of Arclight FeudalKings.
2. Download MythicMobs 5.7.1.
3. Start the server.

I found it could be reproduced in the latest Spigot build. It should be considered as a problem of MythicMobs.
It used something from Paper API that we haven't fully supported.
