Bug in SharedCache handling of Natural-id
-----------------------------------------

                 Key: HHH-7250
                 URL: https://hibernate.onjira.com/browse/HHH-7250
             Project: Hibernate ORM
          Issue Type: Bug
          Components: caching (L2), core
    Affects Versions: 4.1.2, 4.1.0
         Environment: EHCache as shared cache implementation, using read-write strategy
            Reporter: Guenther Demetz


Although configuring org.hibernate.cache.LookupNaturalId cache region large enough and eternal, I always have Warning messages like following:

{noformat}
15:47:27,999  WARN AbstractReadWriteEhcacheAccessStrategy:182 - HHH020008: Cache[hibernate.test.org.hibernate.cache.LookupNaturalId] Key[P##NaturalId[ud1C9grNWA]] Lockable[(null)]
A soft-locked cache entry was expired by the underlying Ehcache. If this happens regularly you should consider increasing the cache timeouts and/or capacity limits
15:47:27,999  WARN AbstractReadWriteEhcacheAccessStrategy:182 - HHH020008: Cache[hibernate.test.org.hibernate.cache.LookupNaturalId] Key[P##NaturalId[ud1C9grNWA]] Lockable[Lock Source-UUID:9ea7be15-29d2-432f-ba0b-961392e0c995 Lock-ID:2]
A soft-locked cache entry was expired by the underlying Ehcache. If this happens regularly you should consider increasing the cache timeouts and/or capacity limits
{noformat}

Debugging into hibernate, I detected that strangely at certain point in StatefulPersistenceContext.java 
method RegionAccessStrategy#unlockRegion ist called, without ever calling lockRegion.
This unlockRegion call (in EHCache it clears the entire region!) has no sense here, 
with evidency the removal of previousCacheKey item was intended here indeed.
Please see the pullrequest, it makes the warnings above dissappear.
