@WrapOperation on instantiation causes an ArrayIndexOutOfBoundsException

[KingContaria]

Hi, i am trying to use @WrapOperation to wrap an instantiation but im having some trouble getting it to work:

My working Redirect:

    @Redirect(
            method = "startIntegratedServer(Ljava/lang/String;Lnet/minecraft/util/registry/RegistryTracker$Modifiable;Ljava/util/function/Function;Lcom/mojang/datafixers/util/Function4;ZLnet/minecraft/client/MinecraftClient$WorldLoadAction;)V",
            at = @At(
                    value = "NEW",
                    target = "Lnet/minecraft/util/UserCache;"
            )
    )
    private UserCache wrapUserCache(GameProfileRepository profileRepository, File cacheFile) {
        if (...) {
            return ...;
        }
        return new UserCache(profileRepository, cacheFile);
    }

My non-working attempt at a WrapOperation:

    @WrapOperation(
            method = "startIntegratedServer(Ljava/lang/String;Lnet/minecraft/util/registry/RegistryTracker$Modifiable;Ljava/util/function/Function;Lcom/mojang/datafixers/util/Function4;ZLnet/minecraft/client/MinecraftClient$WorldLoadAction;)V",
            at = @At(
                    value = "NEW",
                    target = "Lnet/minecraft/util/UserCache;"
            )
    )
    private UserCache wrapUserCache(GameProfileRepository profileRepository, File cacheFile, Operation<UserCache> original) {
        if (...) {
            return ...;
        }
        return original.call(profileRepository, cacheFile);
    }

I am using Fabricloader 0.15.1 with MixinExtras 0.3.1. (The log confirms that MixinExtras 0.3.1 is in fact loading correctly). Minecraft version is 1.16.1 using Java 17. The MinecraftDev plugin unfortunately isnt of much help because it doesnt recognize the injector correctly on the Redirect either.

Minecraft crashes with java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 0, the full crash as a text file can be found here.

Apparently there is a little more to it, reproduction steps are:

• create a Mixin specifying two @WrapOperation's
• both have to target the same method
• the second one has to be targetting an instantiation, the order is important

An example repo can be found here.

Fixed in 0.3.2/0.2.2
