Please dont do this. loader 0.15.X includes mixin extras but even before it did, calling some other random mod's classes as your own mod's prelaunch entrypoint is a recipe for disaster. At best you should have been calling the method from your own class's entrypoint rather than telling loader to create a new instantiation.
