this is indeed an iteresting question;
do we have anybody here with a better knowledge of J2EE?

I guess if the answer to prev. question is positive this could be a worthy idea

Looks like a nice idea to me.
Will not be backwards compatible but logback is not version 1 yet.
I suggest that you create a Jira item for this /and maybe attach a patch/

Looks pretty weird to me. Diego what folder is jcl-over-slf4j-1.5.2.jar in?
Do you have another copy in shared tomcat libraries? Or together with tomcat own jars?
