/**
* A common annotation to declare that annotated elements cannot be {@code null}. 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 Spring API.
*
* Should be used at parameter, return value, and field level. Method overrides should repeat parent {@code @NonNull} annotations unless
* they behave differently.
*
* Use {@code @NonNullApi} (scope = parameters + return values) to set the default behavior to non-nullable in order to avoid annotating
* your whole codebase with {@code @NonNull}.
*
* @since 3.7
* @see NonNullApi
