MySQL Connector/J 8.0 Developer Guide
Some exceptions have been removed from Connector/J going from version 5.1 to 8.0. Applications that used to catch the removed exceptions should now catch the corresponding exceptions listed in Table 4.3 below.
Some of these Connector/J 5.1 exceptions are duplicated in the com.mysql.jdbc.exception.jdbc4 package; that is indicated by “[jdbc4.]” in their names in Table 4.3.
