/**
 * Class-level annotation that indicates to register instances of a class
 * with a JMX server, corresponding to the {@code ManagedResource} attribute.
 *
 * Note: This annotation is marked as inherited, allowing for generic
 * management-aware base classes. In such a scenario, it is recommended to
 * not specify an object name value since this would lead to naming
 * collisions in case of multiple subclasses getting registered.
