Ralph Goers commented on SLF4J-192:
-----------------------------------

Feel free to read [https://issues.apache.org/jira/browse/LOG4J2-124] and see the justification that was used there. 

But if shutdown() wasn't valuable the implementation wouldn't provide it either. So it comes back to the opinion of whether the argument that people only want to use the API is valid or not. Calling shutdown() is pretty much like calling close(). Yes, you can let the OS do it but some things don't implicitly close as well as others, so virtually any application should call shutdown() if it really wants everything to be handled nicely.

> There needs to be a way to shutdown logging and flush async appenders so when a process is closing, all log events are written before the process is closed.
> Should ILoggerFactory have a shutdown or stop method?  It could shutdown whatever logging back end I'm using?
> For log4j it would call - org.apache.log4j.LogManager.getLoggerRepository().shutdown();
> For logback it would call - loggerContext.stop()
> Other back ends - ???
> This is required to allow me to not reference logging back ends explicitly in my code to shutdown successfully without losing events.
> Discussion about this is happening on the user list at -
