/**
* A common Reactor annotation (similar to Spring one) to declare that parameters and return
* values are to be considered as non-nullable by default for a given package.
* Leverages JSR 305 meta-annotations to indicate nullability in Java to common tools with
* JSR 305 support and used by Kotlin to infer nullability of Reactor API.
*
* <p>Should be used at package level in association with {@link Nullable}
* annotations at parameter and return value level.
