When cache logging is debug-level:
Code:
18:36:37,078 DEBUG CacheFactory:32 - cache for: net.buildercom.retriever.hibernate.Parameter usage strategy: read-write
18:36:37,208 DEBUG CacheFactory:32 - cache for: net.buildercom.retriever.hibernate.Profile usage strategy: read-write

18:36:37,338 DEBUG CacheFactory:32 - cache for: net.buildercom.retriever.hibernate.User usage strategy: read-write
I used exactly the same approach as is mentioned in Hibernate and EHCache docs, but I always finish getting this Exception. Do you have any idea what can cause the problem?
