My point is you have to learn about it. There is no code completion to 
help you.
Maybe you can imagine this is formatting a date because there is some 
format
given, but I can't tell whats the "date" parameter for. I would have to 
read the
docs.

I don't want to force our users reading docs except our own. You could
argue slf4j needs some doc reading itself, but many developers may have 
done so already.
Its more widespread and probably a better investment of time.

If there is a lot of code hidden from you, then there is a lot code
which might be buggy. Nobody prevents you to use that framework if you
like it that much, but that is nothing which a framework like Struts
should dictate. Instead I believe Struts should stick to common sense
wherever possible, and logging is one of these cases.

When it comes to logging i am a purist. People already complain because
there are too many logging solutions around today, I don't think it 
would
make any sense to have something special for Struts. There is some stuff
people can use, why are we not using what everybody else uses?

In regards to Onyx, I have a few more reasons why I would like to avoid 
its
introduction. In example:

  - maintained by a single person - who fixes the bugs, when there are 
some? See OGNL.
  - in 2013 only two commits were made - no very active
  - haven't seen the package on maven central repos
  - not wide spread, 18 downloads for each version
  - small version number tells me there is not yet trust in stability

For technical reasons I don't like it's syntax and think it's way to 
much
reflection for solving a simple problem.

To be honest (and sorry, Chris, I really think it was lot of work and 
you
are quite talented) I would prefer to the custom logging we have and 
know
instead of using a pretty unknown, exotic logging wrapper.

That's my two cents, and now I will shut up for a few days on the matter
to give others space to breath.

Thanks!
Christian
