> Method NaturalIdXrefDelegate#cache() misses to remove obsolete entry in naturalIdToPkMap when NaturalId values changed,
> thus NaturalIdAccess delivers results even by searching with obsolete values (see attached Testcase).
> Cause:
> following instruction is missing in Method NaturalIdXrefDelegate#cache():
> if ( initial != null ) {
> 	if ( areSame( naturalIdValues, initial.getValues()) ) {
> 		return false;
> 	}
> 	naturalIdToPkMap.remove(initial); // <-- this instruciton is missing
> }
