    Description

      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:

      Predicate<Foo> predicate = FalsePredicate.INSTANCE;
      

      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.
