Galder Zamarreño commented on ISPN-1281:
----------------------------------------

Manik, hashes are 4 byte integer in the protocol, they're not variable length numbers, so I don't see negative numbers being a problem:

> This is to minimise the collisions as reported in ISPN-1275.  It isn't a complete solution but drastically reduces the probability of collision if the hash space spans Integer.MIN_VALUE -> Integer.MAX_VALUE.
