Hi Steve,

com.mysql.jdbc.exceptions.MySQLTransientException extends SQLException rather than SQLTransientException because the latter was introduced in JDBC 4.0 (Java 1.6):

Connector/J supports both JDBC 3 and JDBC 4, and discovers which runtime you are using dynamically. What you are looking for is found in com.mysql.jdbc.exceptions.jdbc4.MySQLTransientException:

public class MySQLTransientException extends SQLTransientException ...

If you're curious about how Connector/J does discovery of the JRE in use, look at the static block in com.mysql.jdbc.ConnectionImpl, which calls com.mysql.jdbc.Util's isJdbc4() method.

Hope that helps!
