> As a stopgap solution for LOG4J2-406, all MBeans are unregistered when a
> LoggerContext is stopped.
> In an application server, multiple web applications can be deployed and
> undeployed independently and a better solution would only unregister the
> MBeans associated with the web application that is being undeployed.
> Current MBean ObjectNames look like this (simplified):
> {code}
> ...StatusLogger
> ...ContextSelector
> ...LoggerContext,ctx=%s
> ...LoggerConfig,ctx=%s,name=%s
> ...Appender,ctx=%s,name=%s
> ...
> {code}
> Assuming that every web application has a unique name, and this name becomes
> the name of the LoggerContext, then one solution would be to create
> StatusLogger and ContextSelector MBeans that have the LoggerContext name in
> their ObjectName:
> {code}
> ...StatusLogger,ctx=%s
> ...ContextSelector,ctx=%s
> ...LoggerContext,ctx=%s
> ...LoggerConfig,ctx=%s,name=%s
> ...Appender,ctx=%s,name=%s
> ...
> {code}
> This way, every web application would have its own StatusLogger and
> ContextSelector MBeans. The MBeans may point to the same (shared) underlying
> StatusLogger and ContextSelector objects. When a web application is
> undeployed, unregistering all MBeans associated with the LoggerContext will
> not affect any MBeans associated with another web application (which has it
> own, separate, LoggerContext).
