You can't do a HashMap with a byte[] as the Key, unfortunately. You'll have to use a TreeMap (where you can specify a comparator), use a wrapping class, or you could even make it a HashSet or TreeSet with RegionLoad as the only type (and then write a comparator for RegionLoad which compares the regions).
