question: public void checkKey ( Object key ) throws PartitionedRegionException { if ( ! hasHash ) { return ; } if ( key == null ) { return ; } int expected = key . hashCode ( ) ; if ( expected == keyHash ) { return ; } throw new PartitionedRegionException ( "Object hashCode inconsistent between cache peers. Here = " + expected + "; peer calculated = " + keyHash ) ; }
target:  If possible, validate the given key's hashCode against any that was returned by the peer.
