Reading an invalid DATE value might throws unchecked exceptions instead of SQLException

With the default sql_mode (no NO_ZERO_IN_DATE), the server accepts and stores dates with a zero day or month, for example:

CREATE TABLE t (a DATE);
INSERT INTO t VALUES ('2000-03-00');

Reading such a value with several getters makes the driver throw exceptions that are not SQLException, which applications do not catch and whose message does not say which value was at fault

A JDBC getter must report a value it cannot represent through an SQLException only.
