[Building Sakai] Problem Bringing up a Sakai 2.9.1

[Aaron Zeckoski]

You should not include the slf4j jars there as they won't contribute
to this and removing them will probably break things.

The real solution for this issue is to stop using JCL and use slf4j or
something like that but that is a pretty major change and not
something we can do for 2.9.1.
Ideally, no apps should include their own copy of log4j*.jar though.
