> I would like to create a custom logger, while reusing the
> org.apache.logging.log4j.core.Logger functionality.
> The following two changes would make subclassing possible:
> * change visibility of method Logger$PrivateConfig#logEvent(LogEvent) (line
> 265) from protected to public
> * change visibility of method LoggerContext#newInstance(LoggerContext,
> String) (line 310) from private to protected
> My use case is that I want to create an asynchronous Logger for low latency
> logging.
> This custom logger hands off control to a separate thread as early as
> possible. In my case, AsynchAppender is not a good match for my requirements,
> as with that approach (a) the logging call still needs to flow down the
> hierarchy to the appender, doing synchronization and creating objects at
> various points on the way, and (b) when serializing the LogEvent, the
> getSource() method is always called, which is expensive.
