  * <p> An application obtains a service loader for a given service by invoking
- * one of the static {@code load} methods of ServiceLoader. If the application
- * is a module, then its module declaration must have a <i>uses</i> directive
- * that specifies the service; this helps to locate providers and ensure they
- * will execute reliably. In addition, if the service is not in the application
- * module, then the module declaration must have a <i>requires</i> directive
- * that specifies the module which exports the service.
