/**
 * Jackson {@code Module} for {@code spring-authorization-server}, that registers the
 * following mix-in annotations:
 *
 * <ul>
 * <li>{@link UnmodifiableMapMixin}</li>
 * <li>{@link HashSetMixin}</li>
 * <li>{@link OAuth2AuthorizationRequestMixin}</li>
 * <li>{@link DurationMixin}</li>
 * <li>{@link JwsAlgorithmMixin}</li>
 * <li>{@link OAuth2TokenFormatMixin}</li>
 * </ul>
 *
 * If not already enabled, default typing will be automatically enabled as type info is
 * required to properly serialize/deserialize objects. In order to use this module just
 * add it to your {@code ObjectMapper} configuration.
 *
 * <pre>
 *     ObjectMapper mapper = new ObjectMapper();
 *     mapper.registerModule(new OAuth2AuthorizationServerJackson2Module());
 * </pre>
 *
 * <b>NOTE:</b> Use {@link SecurityJackson2Modules#getModules(ClassLoader)} to get a list
 * of all security modules.
