Apache Log4j 2.0-beta6 requires a minimum of Java 6 to build and run. Basic compatibility
Log4j 1.x is provided through the log4j-1.2-api component, however it does not implement some
of the
very implementation specific classes and methods. The package names and Maven groupId have
been changed to
org.apache.logging.log4j to avoid any conflicts with log4j 1.x.
