    This class is a clone of org.springframework.lang.Nullable

    A common Aspectran 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 Aspectran API.

    Should be used at parameter, return value, and field level. Methods override should repeat parent @Nullable annotations unless they behave differently.

    Can be used in association with @NonNullApi or @NonNullFields to override the default non-nullable semantic to nullable.
