Annotation Interface StringOrArray

@Target({FIELD,METHOD,PARAMETER})
@Retention(RUNTIME)
public @interface StringOrArray

Marks a String[] field that can be either a single JSON string or an array of strings. Equivalent to @JsonSerialize(using = StringOrArraySerializer.class) and @JsonDeserialize(using = StringOrArrayDeserializer.class).

With Jackson 2, the meta-annotation expands automatically via JacksonAnnotationsInside. With Jackson 3, the KeycloakAnnotationIntrospector3 handles this annotation directly.
