Ceki Gulcu commented on LBCLASSIC-33:

With revision 1945, whenever the LoggerContext is reset, any associated JMXConfigurator instances are unregistered from the MBeanServer. 

However, applying the techniques outlined in Frank Kieviet's blog (Thanks Joern), I don't seem to be able to have JMXConfigurator garbage collected when the web-app is stopped. (However, when the web-application is stopped and restarted, there is no accrual of LoggerCcontext objects. I am still investigating the issue and will keep you posted.

> There should be a way to shutdown the JMX plugin. Or more generally an API to shut down the Logback system in its entirety: flush buffers, close files etc. It must be decided what to do if a log request arrives when or after logback is shutting down.
