> StringUtils has method defaultIfEmpty and ObjectUtils has defaultIfNull. A
> parallel method is missing from ArrayUtils, and would provide a shorthand way
> of normalizing arrays. My first inclination was nullIfEmpty because no
> simple default value is readily available or easy to specify. But Henri
> mentioned that defaultIfEmpty might better parallel the other
> implementations. That option would work okay for me, as I can just specify
> null as the default.
