Plugin crashes server on startup

[Ambercode0]

WorldEdit Version

7.3.18 beta 1

Platform Version

Paper 1.21.11-54

Confirmations

• I am using the most recent Minecraft release.
• I am using a version of WorldEdit compatible with my Minecraft version.
• I am using the latest or recommended version of my platform software.
• I am NOT using a hybrid server, e.g. a server that combines Bukkit and Forge. Examples include Arclight, Mohist, and Cardboard.
• I am NOT using a fork of WorldEdit, such as FastAsyncWorldEdit (FAWE) or AsyncWorldEdit (AWE)

Bug Description

Server crashes on startup due to WorldEdit fatal error. Removing the plugin makes the server work correctly.

Expected Behavior

I expected the plugin to work on Paper 1.21.11 with Java 25 LTS

Reproduction Steps

Use GraalVM JDK 25
Use Paper 1.21.11-54
Use WorldEdit version 7.3.18 beta1.
Server will not start.

Please attach the full logs, there is probably another error.

WE crashes on Paper 1.21.11 build 54 because it is built for Mojang mappings but accidentally is missing the MANIFEST entry to indicate this, so with build 54's remapping in effect, it remaps stuff into a broken state. TEMPORARY fix is the user downgrading the Paper build, but the actual fix is here on WE's side: https://docs.papermc.io/paper/dev/project-setup/#mojang-mappings
