Indeed!
Yes it does. It was used mainly for validating method parameters, using
ValidationUtils if I recall correctly. However, during build [lang] API is
shaded.

Excellent feedback Benedikt! I'm not up to date to Java 8 - still working in a
bunch of projects with Java6 and 7. I'll take a further look at the existing
predicates in Java 8 to investigate whether it makes sense to include all the
predicates in the patch or not.
Thanks a lot!Bruno

Nice to see same action in the functor component again. Does functor have a
dependency on lang? Usually we try not to have dependencies between
components...
Further more I don't really see the use case for this addtion. Releasing
functor for Java 7 doesn't make much sense to me. Functor and Java 8 lambdas
are a perfect match. But if we target Java 8, one could simply write:
StringUtils::isEmpty
No need to define a separate predicate implementation...
