a really tricky idea:

public Object deepClone()
{
	try
	{
		ByteArrayOutputStream b = new ByteArrayOutputStream();
		ObjectOutputStream out = new ObjectOutputStream (b);
		out.writeObject (this);
		ByteArrayInputStream bin = new ByteArrayInputStream (b.toByteArray());
		ObjectInputStream oi = new ObjectInputStream (bin);
		return (oi.readObject());
	}
	catch (Exception e)
	{
		System.out.println ("Exception : " + e.getMessage());
		return null;
	}
}
