Review comment:
This can be replaced by `return firstNonNull(values) == null`, although then
you're doubling up on the null check.

> Add anyNull(Object ...) to ObjectUtils
> --------------------------------------
>
> Key: LANG-1421
> URL: https://issues.apache.org/jira/browse/LANG-1421
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 3.8
> Reporter: Sandra Parsick
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We looked for
> {code:java}
> ObjectUtils.anyNull(Object ...)
> {code}
> We found LANG-781 but when we look in the Pull Request, we found methods like
> anyNotNull and allNotNull.
> We would still like to add anyNull and allNull as opposite of these.
