Coders work with what they have. The work itself is shaped by the tools the workers use to produce it. If you give workers inadequate tools, you can't expect high quality. Java currently doesn't provide any decent (general) solution for the problem of nullability - JSR-305 is a failed spec, Optional is very verbose, doesn't work for many use cases (e.g. isn't Serializable) and funnily enough there's no guarantee the Optional instance is non-null, value types (primitive and the preview support for complex ones) obviously covers only very specific use cases.
