LifeCycleCallbackCollection This class collects the classes and methods that have been configured in web.xml with postconstruct/predestroy callbacks, or that contain the equivalent annotations. It is also responsible for calling the callbacks. This class is not threadsafe for concurrent modifications, but is threadsafe for reading with concurrent modifications.
