New Revision: 1527626

Log:
Fixed a subtle flaw in the GenericDelegator.findOne method. When a database 
query returns no result, GenericValue.NULL_VALUE is put in the pk cache - so 
future findOne calls will know the entity value doesn't exist. But the findOne 
method never checked for GenericValue.NULL_VALUE in cache gets, so the database 
was queried again for an entity value we already know doesn't exist.
