PS2, Line 44:         int h = Math.abs(dId ^ entityHashValue);
            :         if (h < 0) {
            :             // Math.abs returns a negative when the value is 
Integer.MIN_VALUE
            :             // ensure h is not negative since result sign of m % 
n is the same as m
            :             h = 0;
            :         }
            :         return table[h % size];
            :
would table[Math.abs((dId ^ entityHashValue) % size)] be a better pattern?  
seems like this is the goal
