Ben Slater commented on CASSANDRA-12744:

I tried this patch out. It definitely seems to improves distribution to 
something like what you'd expect. Didn't notice any issues.

> Randomness of stress distributions is not good

> The randomness of our distributions is pretty bad.  We are using the 
> JDKRandomGenerator() but in testing of uniform(1..3) we see for 100 
> iterations it's only outputting 3.  If you bump it to 10k it hits all 3 
> values. 
> I made a change to just use the default commons math random generator and now 
> see all 3 values for n=10
