Gary D. Gregory commented on LANG-804:
--------------------------------------
If you remove the == 0 checks, you'd get a / 0 error on 0 input on the % 2
checks. The current code is pretty simple and straightforward. What would be an
alt impl?
> Redundant check for zero in HashCodeBuilder ctor

> Project: Commons Lang
> Issue Type: Improvement
> Reporter: Sebb
> Priority: Minor

> The HashCodeBuilder(int, int) ctor checks both parameters for zero, as well
> as checking for an odd number.
> Zero is never odd, so the zero check could be eliminated.
