public @interface Nullable
A common annotation to declare that annotated elements can be
null under some circumstance. 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 Micronaut API.
Should be used at parameter, return value, and field level. Methods override should repeat parent @Nullable annotations
unless they behave differently.
