java.lang.Objectorg.hibernate.cache.NonstrictReadWriteCache
public class NonstrictReadWriteCache
Caches data that is sometimes updated without ever locking the cache. If concurrent access to an item is possible, this concurrency strategy makes no guarantee that the item returned from the cache is the latest version available in the database. Configure your cache timeout accordingly! This is an "asynchronous" concurrency strategy.
