Major Description
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();
}
