Review Comment:
I can try to run benchmarks with that and see how that turns out.....but
with the current logic (below) we see 7-9% better performance consistently.
Could that be misleading by any chance or maybe worth sticking to that?
```java
int msb = ((int) hash[0] >>> Integer.SIZE) >>> 1 + ((int) hash[1] >>>
Integer.SIZE) >>> 1;
int lsb = ((int) hash[0]) >>> 1 + ((int) hash[1]) >>> 1;
```
