 - ConnectionEvent field changed for serialization
 - Date toString classes no longer use SimpleDateFormat
 - Timestamp doesn't call through an overridable method in its constructor
 - Timestamp now checks the String passed to valueOf() using a regex
 - Properties now specifies a buffer size to avoid a user-inescapable warning
