> PredicateUtils (all|any)Predicate type misbehaviour Array vs. Collection

> Key: COLLECTIONS-537
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-537
> Project: Commons Collections
> Issue Type: Bug
> Components: Functor
> Affects Versions: 4.0
> Reporter: Frank Jakop
> Fix For: 4.1

>
> Migrating from collections-generic to collections4 we encountered a type
> problem with PredicateUtils. When you look at the method anyPredicate(), the
> signature with array is typed with "Predicate<? super T>" whereas the
> signature with Collection is typed "? extends Predicate<T>", so the both
> methods are not equivalent.
> We think both methods should have the same types, so it would not break
> compatibility with a lot of legacy code.
