I didn't realize that org.spongepowered.asm.lib is used by InjectionPoints, and I haven't realized someone already used them. As of 0.2.0.69, we use org.objectweb.asm globally.

PS. Could you make your injection point namespaced in some manner?

Though I'm not sure if we should be making Mixin use the global ASM library, for interop with Sponge...

Wait on this issue. I'll get back to you.

Contacted Sponge, reverting on our side

Alright. Let me know if you still think its a good idea to namespace my @InjectionPoint.AtCode

It still is, yes, I think.

Makes sense, will do. 👍
