/**
 * Jersey server-side application handler.
 * 

 * Container implementations use the {@code ApplicationHandler} API to process requests
 * by invoking the {@link #handle(ContainerRequest) handle(request)}
 * method on a configured application  handler instance.
 * 
 * 

 * {@code ApplicationHandler} provides two implementations of {@link jakarta.ws.rs.core.Configuration config} that can be injected
 * into the application classes. The first is {@link ResourceConfig resource config} which implements {@code Configuration}
 * itself and is configured by the user. The resource config is not modified by this application handler so the future reloads of
 * the application is not disrupted by providers found on a classpath. This config can
 * be injected only as {@code ResourceConfig} or {@code Application}. The second one can be injected into the
 * {@code Configuration} parameters / fields and contains info about all the properties / provider classes / provider instances
 * from the resource config and also about all the providers found during processing classes registered under
 * {@link ServerProperties server properties}. After the application handler is initialized both configurations are marked as
 * read-only.
 * 
 * 

 * Application handler instance also acts as an aggregate {@link ContainerLifecycleListener} instance
 * for the associated application. It aggregates all the registered container lifecycle listeners
 * under a single, umbrella listener, represented by this application handler instance, that delegates all container lifecycle
 * listener method calls to all the registered listeners. Jersey {@link Container containers} are expected to invoke
 * the container lifecycle methods directly on the active {@code ApplicationHandler} instance. The application handler will then
 * make sure to delegate the lifecycle listener calls further to all the container lifecycle listeners registered within the
 * application. Additionally, invoking the {@link ContainerLifecycleListener#onShutdown(Container)} method on this application
 * handler instance will release all the resources associated with the underlying application instance as well as close the
 * application-specific {@link InjectionManager injection manager}.
