Mixin conflict with jline4mcdsrv – DedicatedServer$ConsoleHandlerThreadMixin fails to apply

[TheKidThatCodes]

Describe the issue

Worldthreader fails to launch due to a mixin conflict when used alongside the jline4mcdsrv mod.

Both mods inject into the same method MinecraftDedicatedServer$1::run() causing an InvalidInjectionException.

Crash Report

Mixin apply for mod worldthreader failed:

InvalidInjectionException: @At("INVOKE") on net/minecraft/server/dedicated/MinecraftDedicatedServer$1::getNull with priority 1000 cannot inject into net/minecraft/server/dedicated/MinecraftDedicatedServer$1::run()V
merged by org.chrisoft.jline4mcdsrv.mixin.DServerConsoleThreadInject with priority 1000

This causes the server to crash during launch:

java.lang.RuntimeException: Mixin transformation of net.minecraft.server.dedicated.MinecraftDedicatedServer$1 failed
Caused by: MixinApplyError: Mixin [...] FAILED during APPLY

Steps to Reproduce

1. Install worldthreader
2. Install jline4mcdsrv (https://github.com/chirs241097/jline4mcdsrv)
3. Launch server
4. Server crashes with mixin conflict

Environment

• Minecraft: 1.21.6
• Fabric Loader: 0.16.14

Suggested Fix by ChatGPT

Consider reducing the mixin injection priority for DedicatedServer$ConsoleHandlerThreadMixin, or changing the injection point to avoid overlap with DServerConsoleThreadInject. Alternatively, a compatibility mixin for environments with jline4mcdsrv could be added.
