Coming from functional languages, I really really tried to make optional work in our code base. However, it's inability to interact with checked exceptions or even slightly unusual control flow make it a real pain. It feels like fighting the language. My current suggestion is to pick a nullability annotation, and then wire it through your compiler and IDE, so it tells you if you forgot null checks, or made a superfluous null check on something annotated non-null.
