Remko Popma resolved LOG4J2-392.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 2.0-rc1

I modified {{BaseConfiguration.stop()}} to ensure that all loggers and appenders are stopped in this order:
# --AsyncLogger Disruptor thread-- (this is not possible yet until we have a solution for LOG4J2-493)
# AsyncLoggerConfig Disruptor thread(s)
# AsyncAppender(s)
# other appenders
# non-async LoggerConfigs
# root LoggerConfig (if non-async)

Committed in revision 1565254.
Please verify and close.
