Answer 1

With the latest version of log4j2, all create the APIs like

PatternLayout.createLayout, 
FileAppender.createAppender, 
LoggerConfig.createLogger 

have become deprecated, it's better to use a custom log ConfigurationFactory along with ConfigurationBuilder for defining the log configuration programmatically.
