> Description:
> HashMap.HashMapEntrySet.contains(Object) cannot find custmized entry if the entry hasn't  override the equal method.
> Testcase:
>     @SuppressWarnings("unchecked")
>     public void test_EntrySet(){
>         HashMap map = new HashMap();
>         map.put(new Integer(1), "ONE");
>         
>         Set entrySet = map.entrySet();
>         Iterator e = entrySet.iterator();
>         Object a = e.next();
>         assertFalse(e.hasNext());
>         
>         Map.Entry entry = new MockEntry();
>         assertTrue(entrySet.contains(entry));
>         entrySet.remove(entry);
>         assertFalse(entrySet.contains(entry));
>     }
>     
>     private static class MockEntry implements Map.Entry{
>         public Object getKey() {
>             return new Integer(1);
>         }
>         public Object getValue() {
>             return "ONE";
>         }
>         public Object setValue(Object object) {
>             return null;
>         }
>     }
> Result:
> RI can pass this test while harmony will fail.
