public class PersistentApplicationEventMulticaster
extends AbstractApplicationEventMulticaster
implements IncompleteEventPublications, SmartInitializingSingleton

An ApplicationEventMulticaster to register EventPublications in an EventPublicationRegistry so that potentially failing transactional event listeners can get re-invoked upon application restart or via a schedule.

Republication is handled in afterSingletonsInstantiated() inspecting the EventPublicationRegistry for incomplete publications and
