> Considering the following test case: 
> class MockObjectInputStream extends ObjectInputStream {
> 	protected MockObjectInputStream() throws IOException, SecurityException {
> 		super();
> 	}
> 	@Override
> 	protected Object readObjectOverride() throws IOException, ClassNotFoundException {
> 		System.out.println("readObjectOverride");
> 		return super.readObjectOverride();
> 	}
> }
> public class ObjectInputStreamTest {
> 	
> 	public static void main(String[] args) throws Exception {
> 		MockObjectInputStream mock = new MockObjectInputStream();
> 		System.out.println(mock.readObject());
> 	}
> }
> RI outputs:
> readObjectOverride
> null
> while Harmony outputs:
> null
> It seems that in Harmony, subclasses of j.i.ObjectInputStream does not call readObjectOverride()
 when readObject() is called. But RI does.
> I'll create a patch soon, thanks.
