Description

Even a simple example as:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Test {

private static final Logger logger = LogManager.getLogger(Test.class.getName());

public static void main(String[] args)

{ logger.error("Testing..."); }

}

Results in:
