How to turn off htmlunit logging?

[php-coder]

I didn't found how to turn off htmlunit logging. At this moment it produces a lot of noise:

ERROR] runtimeError: message=[An invalid or illegal selector was specified (selector: '*,:x' error: Invalid selector: :x).] sourceName=[http://127.0.0.1:8080/public/jquery/1.9.1/jquery.min.js] line=[4] lineSource=[null] lineOffset=[0]

I have src/test/resources/logback-test.xml file where these messages are turned off but htmlunit doesn't use this file.

How to manage logging for htmlunit in this case?

An update in case it can be helpful to someone else:

The loglevel is set and managed by Maven. Here is the details: https://maven.apache.org/maven-logging.html It uses slf4j and SimpleLogger by default. In order to suppress annoying htmlunit messages, I passed the following options:

-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.DefaultCssErrorHandler=error
-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.html.InputElementFactory=warn
-Dorg.slf4j.simpleLogger.log.com.gargoylesoftware.htmlunit.IncorrectnessListenerImpl=error

In order to use them always and by default, I put these lines into .m2/jvm.config file within a project.
