> I want to use the async logger with Log4j2, but i find that follow the
> official document, i can not get a real async logger.
> I read this doc:
> [https://logging.apache.org/log4j/2.x/manual/async.html|https://logging.apache.org/log4j/2.x/manual/async.html.]
> In this part "Mixing Synchronous and Asynchronous Loggers", i copy the xml
> config and run a test, it shows that the "com.foo.Bar" is not an async
> logger.
>
> From the test, i think it shuold be
> "org.apache.logging.log4j.core.async.AsyncLogger", but it is
> "org.apache.logging.log4j.core.Logger".
