Description

When two accessors target the same lowercase single-letter field, one with implicit name and one with an explicit name, such as below, the game crashes with the following error:

Mod A:

@Accessor("x")
int getX();

Mod B:

@Accessor
int getX();

Error

Reproduction

This repo can be used to reproduce the issue.

Analysis

It seems like AccessorInfo#inflectTarget always returns X for Mod B's accessor, while the name is x for Mod A's accessor. While Mod B's accessor works fine by itself, (mixin somehow finds the right field even though AccessorInfo#inflectTarget returns a captical X), having both accessors does not work. Since MixinApplicatorStandard#isAlreadyMerged directly compares the targets for both accessors, which is x:I for Mod A and X:I for Mod B. Since the targets are not the same, an InvalidMixinException is thrown on line 580 of MixinApplicatorStandard.
