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".
