> The hotspot VM offers a way to avoid having to specify the driver class explicitly when
using the JDBC driver. 
> The DriverManager methods getConnection and getDrivers have been enhanced to support
the Java Standard Edition Service Provider mechanism. JDBC 4.0 Drivers must include the file
META-INF/services/java.sql.Driver. This file contains the name of the JDBC drivers implementation
of java.sql.Driver. For example, to load the my.sql.Driver class, the META-INF/services/java.sql.Driver
file would contain the entry: `my.sql.Driver`
>  
> Applications no longer need to explicitly load JDBC drivers using Class.forName(). Existing
programs which currently load JDBC drivers using Class.forName() will continue to work without
modification.
