/**
* Immediate is a scope that operates like {@link javax.inject.Singleton} scope, except that instances are created as soon as their
* corresponding {@link Descriptor}s are added. When the corresponding {@link Descriptor} is removed from the
* locator the Immediate scope service is destroyed. In particular Immediate scope services are not destroyed if
* the {@link ServiceHandle#destroy()} method is called. Care should be taken with the services injected into
* an immediate service, as they also become virtual immediate services
*
* The Immediate scope is not automatically handled by a new ServiceLocator. In order to enable the Immediate scope
* the user can either add an implementation of {@link Context} which handles it or it can use the
* {@link org.glassfish.hk2.utilities.ServiceLocatorUtilities#enableImmediateScope(ServiceLocator)} method.
