Disable logging from log4j 2 library, how?

I'm using log4j 2 for logging and want to turn off the log messages from the library itself, e.g.:

2017-02-20 07:36:38,160 main DEBUG Took 0.001600 seconds to load 0 plugins from package org.apache.logging.log4j.test

I got the following in my log4j2.XML file but I still get DEBUG messages like the one above:

<Logger name="org.apache.logging" level="error" additivity="false">
    <AppenderRef ref="STDOUT" />
</Logger>

This question is not a duplicate of Disabling Log4J Output in Java because I don't want to turn off all output, only the output from the log4j 2 library itself. So I still want my code to generate log output.

Be careful if you are migrating from log4j 1.x as I am trying to do. I've correctly configured log4j2 but somehow there was still log4j as inherited dependency (and a inherited configuration) in my project. The side effect of that is that both log4j are able to log, this is pretty annoying and pretty impossible to debug.

You can control the internal logging Log4j2 prints to the console with the status attribute at the top of the configuration file.

I would recommend that you switch off the verbose debug-level logging but keep the warn and error level logging so you get informed when something goes wrong.

To do this, change the beginning of the configuration file to this:

<Configuration status="WARN">

Set logging root level to <Root level="off">
