NPE in NaturalIdResolutionCache
-------------------------------
Key: HHH-7241
URL: https://hibernate.onjira.com/browse/HHH-7241
Project: Hibernate ORM
Issue Type: Bug
Affects Versions: 4.1.2
Environment: Hibernate 4.1.2, hsqldb 2.2.8
Reporter: Neukomm
Attachments: NaturalIdResolutionCacheNPETest.zip
Starting with hibernate-core version 4.1.2,
NaturalIdXrefDelegate$NaturalIdResolutionCache.cache throws NullPointerException in cases
where the id is not yet known. hibernate-core 4.1.1 works fine.
I've attached a test case that fails in 4.1.2, but runs fine with 4.1.1.

Would it be reasonable to just add a null check at the beginning of
{{NaturalIdResolutionCache.cache}} ?
Obviously the newly-saved object won't be cached but that seems better than throwing
an exception. Ideally the call to {{NaturalIdResolutionCache.cache}} would be delayed
until the id value is known.
{code}
public boolean cache(Serializable pk, Object[] naturalIdValues) {
final CachedNaturalId initial = pkToNaturalIdMap.get( pk );
if ( initial != null ) {
if ( initial.isSame( naturalIdValues ) ) {
return false;
}
naturalIdToPkMap.remove( initial );
}
final CachedNaturalId cachedNaturalId = new CachedNaturalId( persister,
naturalIdValues );
pkToNaturalIdMap.put( pk, cachedNaturalId );
naturalIdToPkMap.put( cachedNaturalId, pk );
return true;
}
{code}
