    Description

      5 August 2015 --The Apache Logging Services™ Project Management Committee (PMC) has announced that the Log4j™ 1.x logging framework has reached its end of life (EOL) and is no longer officially supported.

      https://blogs.apache.org/foundation/entry/apache_logging_services_project_announces

      A whole framework log4j2 upgrade has to be synchronized, partly for improved performance brought about by log4j2.
