Hm, the root logger name is the empty string, so it sounds like we need a
special case for that.
"I tried using a simple log4j2.xml instead, but that does not seem to help"
What do you mean? You use an XML config file and you get the same exception?
That does not seem possible. Or is the config not doing what you expect.
