MemoryAggregationRepository	A memory based AggregationRepository which stores Exchanges in memory only.
OptimisticLockRetryPolicy	Class to control how failed optimistic locks are tried.
UseLatestAggregationStrategy	An AggregationStrategy which just uses the latest exchange which is useful for status messages where old status messages have no real value.
