-----------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-4750
                 URL: https://issues.apache.org/jira/browse/HARMONY-4750
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Sean Qiu


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.
