The JVM (probably a ClassLoader) finds the class of that name and loads a Class<T> object into the memory used by the JVM. In the case of the JDBC connector classes, I believe there is a static initialiser block which initiates the connection to the database.

Whenever a class gets loaded, all of its static variables get initialized and static initializer blocks get fired. You know, 'static' applies on the class itself and has no instance dependence.
