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());
