Instead of manipulating byte code at runtime, wouldn't it make more sense to use an annotation processor to just create a specialized UnsafeArrayList for each input type you need? With something like JavaPoet, it's fairly easy to do as well. It feels a lot safer than manually creating byte code like that. Let javac do that for you.
