I am using hibernate 3.1. I have multiple transactions in each session. It seems that the items I put into the cache are only gettable for those sessions created later. It looks pretty weird to me that the DefaultLoadEventListener.loadFromSecondLevelCache(LoadEvent, EntityPersister, LoadType) uses the session timestamp as a transaction timestamp and passes it to ReadWriteCache.get(Object key, long txTimestamp). This prevents my loading code in a later transaction started from the same session hitting the cache. Does anyone know if this is designed that way?

If it is designed that way, why doesn't Session.clear() reset the timestamp?
