Oliver Lietz commented on SLING-5589:
-------------------------------------
It is part of the Validation API and is in no way related to collections. There
is also a Predicate in [Commons
Functor|https://commons.apache.org/proper/commons-functor/index.html] but no
release yet.
> Remove dependency commons-collections

> The only class (interface) used from commons-collections is
> [{{org.apache.commons.collections.Predicate}}|http://commons.apache.org/proper/commons-collections/javadocs/api-3.2.2/org/apache/commons/collections/Predicate.html].
> We should use
> [{{java.util.function.Predicate}}|https://docs.oracle.com/javase/8/docs/api/java/util/function/Predicate.html]
> (which requires Java 8) or provide our own interface.
