> I set properties
> Log4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
> to make all logging async; it works quite well while my app is up which is
> running on liberty.
> when I try to shut it down with liberty's stop command. Log4j cannot stop
> normally, it looks like that its AsyncLoggerDisruptor.stop(at line 152)
> method want to load class DiscardingAsyncQueueFullPolicy， but the ClassLoader
> cannot be found, so system begin to throws NPE; at the same time log4j
> cannot write any more message, as it cannot get logger any more as system is
> shutting down. so log4j began to thow exception eventually it cause OOME.
> I guess it's async logger issue. so I remove the Log4jContextSelector
> properties and try. it works. I will try sync logger and async appender later.
