>                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-502
>             Project: Commons Collections
>          Issue Type: Improvement
>          Components: Functor
>    Affects Versions: 4.0
>            Reporter: Emmanuel Bourg
>            Priority: Trivial
>
> In {{FalsePredicate}} the {{INSTANCE}} singleton is defined as 
> {{Predicate<Object>}}. In other predicates such as {{TruePredicate}} it's
> defined as {{Predicate<?>}}. In both cases this prevents the declaration of:
> {code}
> Predicate<Foo> predicate = FalsePredicate.INSTANCE;
> {code}
> This will fail to compile.
> I suggest declaring the INSTANCE fields as an ungenerified {{Predicate}}, 
> such that the above example compiles with an unchecked warning.
