Sorry one more time - doesn't works correctly only with second level cache. Works fine without it.

Current test case tested with latest RC builds. Failed method: WithCacheTest.testLoad()

I think the reason is calling method resolveIdentifier() for resolving child entity (BeanB) after retriving parent entity (BeanA) from cache.

It hits database. I can clearly see in log:
27279 [main] DEBUG org.hibernate.SQL null - select beana0_.id as id4_0_, beana0_.parent_id as parent2_4_0_ from BeanA beana0_ where beana0_.id=?
Hibernate: select beana0_.id as id4_0_, beana0_.parent_id as parent2_4_0_ from BeanA beana0_ where beana0_.id=?

> Hibenate should not load any assotiations until it is required. For example, if BeanA has field
> private BeanB parent;
> this field MUST NOT be loaded during BeanA loading, if field is marked as LAZY. It behaviour must have place even if NotFound action does not specified.
