Jean-Noel Rouvignac updated COLLECTIONS-362:
--------------------------------------------

    Description: 
Here is what I mean:

- test 1:
 List l = new ArrayList();
 l.add("test");
 assertTrue( CollectionUtils.filter(l, FalsePredicate.getInstance()) );
 assertTrue(l.isEmpty());

- test 2:
 List l = new ArrayList();
 l.add("test");
 assertFalse( CollectionUtils.filter(l, TruePredicate.getInstance()) );
 assertEquals(1, l.size());
