+Method 2 allows you to specify a logger for your custom step class but implicitly derives the log level from the Root logger in the log4j2.xml configuration file if no logger with the canonical class name exists. Effectively, the log level of the custom step logger will be the same as the log level of the Root logger. 
 
 Method 3 allows you to specify a logger name (which should correspond to a logger configured in the log4j2.xml configuration file). If the logger with the specified logger name does not exist, the Root logger will be returned instead.
