It's worse than that.

When Java finally added a logging library, they added one that no-one had ever heard of before, and which had fundamental flaws. That's why no-one uses it. At the time, log4j existed and was in wide use, but was not represented on the committee.

The author of log4j eventually decided to go a different way and created slf4j / logback. This offering is compatible with log4j and considerably simpler in many ways.

Having not been in the Java world for many years, I was surprised log4j was still in widespread use. But maybe I shouldn't be surprised - whenever we have to interact with Java teams, we always have to tamp down on the tendency towards complexity.
