[logback-user] How to stop all appenders?

[Michael Schall]

This requires me to have access to ch.qos.logback.classic when writing code.
 It does not allow me to switch loggers out without changing code.

We are in the process of moving from log4j to logback.  One requirement
placed on me is to be able to revert back to log4j if something "goes
wrong".  I was hoping that using SLF4J would give me this ability.

I'm trying to achieve writing code only using SLF4J and...

if slf4j-log4j12-1.6.1.jar and log4j-1.2.15.jar are in my production
classpath, I'm logging using log4j.
If log4j-over-slf4j-1.6.1.jar (for third-party
logging), logback-classic-0.9.24.jar, and logback-core-0.9.24.jar are in my
production classpath, I'm logging using logback.

So without changing code, I can switch between logging back ends.

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()

Thoughts?
