Messaging implements a simple, threadsafe and messaging api. Used for cache synchronization. Msg can have several modes: - LockedBy set to ALL (Exclusive Messages): every listener may process it (in parallel), means 1->n. e.g. Cache sync - LockedBy null (non exclusive messages): only one listener at a time - Message listeners may return a Message as answer. Or throw a MessageRejectedException.c
