[logback-dev] jmx plugin, unregistering

I started using the JMX plugin of login, and I wondered how should I shut it down when a web application is restarted. I haven't found a function which unregisters the Configurator MBean. This object holds a reference (through ContextAwareBase) to a Context. I am afraid that not unregistering it causes a memory leak when a web application is restarted.
