It is a "new" feature in Java 1.6.

Not sure about the Google term, but:

https://docs.oracle.com/javase/6/docs/api/java/sql/DriverManager.html

<quote>
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 explictly load JDBC drivers using 
Class.forName(). Existing programs which currently load JDBC drivers 
using Class.forName() will continue to work without modification. </quote>
