org.springframework.osgi.context.DelegatedExecutionOsgiBundleApplicationContext
Interface that redirect the application context crucial methods to a third party executor to allow the initialization to be executed in stages. The interface splits the refresh method in two parts: {@link #startRefresh()} and {@link #completeRefresh()}.
Note: This interface is intended for usage only inside Spring-DM framework. Relying on this interface is highly discouraged. @author Costin Leau
