Example the other way around:

Java code:
```
String select = "SELECT * FROM public.testtable";
statement = connection.prepareStatement(select);
resultSet = statement.executeQuery();

while (resultSet.next()) {
    String str = resultSet.getString(2);
    java.sql.Date date = resultSet.getDate(2);
    System.out.println("As String: " + str);
    System.out.println("As sql.Date: " + date);
    System.out.println("Epoch within sql.Date: " + date.getTime());
}
```

**psql execution:**
```
postgres=# insert into public.testtable(this_is_a_date) values ('1000-01-01');
INSERT 0 1
postgres=# select * from public.testtable;
 id | this_is_a_date
----+----------------
 50 | 1000-01-01
(1 row)
```

**Result with driver 42.7.8:**
```
As String: 1000-01-01
As sql.Date: 1000-01-01
Epoch within sql.Date: -30609795600000
```

**Result with driver 42.7.9:**
```
As String: 1000-01-01
As sql.Date: 0999-12-27
Epoch within sql.Date: -30610227600000
```
