Phosphor Crash Fix

by Elephant1214

Phosphor Crash Fix is a Forge core mod that stops crashes caused by outdated Mixin annotations in Phosphor on 1.12.2.

ForgeServer-side onlyCustom license1.12.2

What it does

Phosphor relies on injection annotations that predate newer Mixin versions, and on some setups this triggers a crash. Phosphor Crash Fix is a simple core mod that updates those annotations so the lighting optimization loads on newer Mixin builds. Few other mods fix this kind of Mixin compatibility, and this one targets the 0.7.x line specifically.

The mod is server-side only, so players join without installing it. Files exist for Forge 1.12.2 only, with 1.0.0 as the latest release from 2024-01-12. The license is custom and the code is not open source, though public links to the source and issue tracker are available.

Key features

  1. Annotation update

    Rewrites Phosphor's outdated injection annotations so they match what newer Mixin builds expect.

  2. Core mod loading

    Loads as a Forge core mod, so the fix applies before Phosphor's mixins are processed.

  3. Mixin 0.7.x fix

    Addresses the 0.7.x Mixin compatibility issue that causes the crash in the first place.

Phosphor Legacy Forge covers 1.8.8 – 1.11.2 and is open source under the GNU General Public License v3.0 or later, with the client or server optional. Alfheim is for 1.12.2, open source under the MIT License, and runs client or server optional, so it targets the same version range without a crash fix.

What the author says

A few other mods fix this in Mixin by adding compatibility for 0.7.x, but this fixes the issue with the mod. This is marked as required on both sides because having Phosphor on the client will still cause the same crash even if you don't load into singleplayer. It is otherwise not required if you don't have Phosphor…
