I'm running tests for a Java/Maven project using Selenium 3.4 and the FirefoxDriver (not the Marionette/Geckodriver). I have Firefox 45.9.0 installed. Our test code uses Log4j2 and I can set the logging level to whatever I like, but no matter what I set it to I get log messages like this in the console:

It looks like something inside the FirefoxDriver, or inside Firefox itself, is logging at a DEBUG level no matter what I set our logging level to.
I looked at this question but I can't figure out how to translate the Python answer to our Java code:
Example Python:
import logging
from selenium.webdriver.remote.remote_connection import LOGGER
LOGGER.setLevel(logging.WARNING)
Our Java code:
DesiredCapabilities capability = DesiredCapabilities.firefox();
FirefoxProfile profile=new FirefoxProfile();
capability.setCapability(FirefoxDriver.PROFILE, profile);
mDriver = new FirefoxDriver(capability);
I've tried several permutations but nothing seems to affect this logging - these messages appear in the console no matter what. Anyone have any way to control this logging?
