public interface InternalDestroyable
Internal framework interface for components that hold static state (caches, daemon threads, etc.) requiring cleanup during application undeploy to prevent classloader leaks. <p>Implementations are registered as named beans in struts-beans.xml (or plugin descriptors) with type InternalDestroyable. During Dispatcher.cleanup(), all registered implementations are discovered via Container.getInstanceNames(InternalDestroyable.class) and invoked automatically.</p> <p>This is not part of the public user API. For user/plugin lifecycle callbacks, use DispatcherListener instead.</p>
