> Given a test case [1], HARMONY will throws ClassCastException while RI works well. This also occurs when cast Hashtable.elements() to Iterator and cast Hashtable.keySet().iterator() to Enumeration.
> [1]
> public void test_HashTable_keys() {
>         Hashtable hashTable = new Hashtable();
>         hashTable.put("key", "value");
>         // cast Enumeration to Iterator
>         Iterator iterator = (Iterator) hashTable.keys();
