While this may provide some benefits and be more flexible, it would
require that in every single instance of our use of JSPWiki (which
now reaches into three or four related projects) we would then have
two logging systems. Log4J, whatever its issues, is still by far the
most widely used Java-based logging package (so far as I know). It's
functional and works well. It is widely understood by our programmers
and contractors.

We have no issue with log4j in any of our other projects (where it
is used very widely), don't have any problems with it "playing well
with other applications", and newness or coolness really doesn't
enter into the decision-making process if that's the motivation.

I would much prefer that we stay with log4j, as this is for myself
only an added complexity, an added redundancy, with little benefit.
