Generic '&' operator / fabric #507
Description
Hello,
i'm developing a fabric mod using the sponge mixins where i need to to invoke a private method from within a mixin.
I created an interface with the method signatures i want to call from the target class. It look like the following:
@Mixin(Screen.class)
public interface IScreen {
@Invoker(remap = true)
<T extends Drawable> T callAddDrawable(T drawable);
@Invoker(remap = true)
<T extends Element & Selectable> T callAddSelectableChild(T child);
}
Now in my implementing (abstract) screen mixin, i can call the "callAddDrawable" method and it works great.
However, calling the "callAddSelectableChild" the same way does ONLY work in dev (gradle runClient) and not if i build the mod and run it with the fabric loader.
I get the following exception:
Mixin apply failed mymod.mixins.json:IScreen -> net.minecraft.class_437: org.spongepowered.asm.mixin.gen.throwables.InvalidAccessorException No candidates were found matching addSelectableChild(Lnet/minecraft/class_364;)Lnet/minecraft/class_364; in net/minecraft/class_437 for mymod.mixins.json:IScreen->@Invoker[METHOD_PROXY]::invokeAddSelectableChild(Lnet/minecraft/class_364;)Lnet/minecraft/class_364; [INJECT Applicator Phase -> mymod.mixins.json:IScreen -> Apply Accessors -> -> Locate -> mymod.mixins.json:IScreen->@Invoker[METHOD_PROXY]::invokeAddSelectableChild(Lnet/minecraft/class_364;)Lnet/minecraft/class_364;]

The other one (callAddDrawable) still works with fabric for some reason. I suspect the problem with the '&' operator of the generic T type of the function.
Enrivonment:
- Java 16 AdoptOpenJDK
- Minecraft 1.17
I don't know if this is a bug with fabric, sponge or my fault and need your help.
Any help is greatly appreciated, thanks.
