Bob Marinier commented on CONFIGURATION-839:
--------------------------------------------
I removed jcl-over-slf4j from my project and everything is working now. It's
hard to immediately tell if something that used to get logged isn't getting
logged anymore, or is getting logged to the wrong place, so I'll have to keep
an eye on it. Also, the removal was not simple. I have a bunch of libraries
that use apache configuration2, and many of them were using jcl-over-slf4j, and
in many cases explicitly excluding commons-logging from configuration2 because
of this. In a couple places I had to reorder dependencies to make sure logging
1.3.0 was picked up instead of 1.2. In the end I had to touch 17 pom files, but
it's working and in fact the poms are cleaner now that I don't have to do
anything special to make configuration2 log over slf4j.
So, I don't think there's anything for you to change code-wise. What I might
suggest is putting a note somewhere (maybe in the release notes?) indicating
that jcl-over-slf4j shouldn't be used anymore, because it's not obvious and the
error messages make it look like something is wrong on your end, even though I
don't think there is.
Thanks for your help working through this.
