JRuby + Rails3 + Unit Tests = "Log" issue?

Hey all,

I am working on a Rails 3.0.7 application that is using JRuby 1.6.3,
running on Debian. I keep encountering an error regarding a missing
"Log" file when I am trying to run some Unit tests (among various
other activities). The cryptic error in question:

LoadError: No such file to load -- Log

Has anyone seen anything like this before? I am baffled as to where to
even begin to solve this. I was able to surpress the same warning when
running `jruby -S rails console` by adding the following lines to /
config/environments/development.rb

config.logger = nil
config.active_record.logger = nil
config.active_controller.logger = nil

Obviously this isn't a sustainable solution as I need my logs and I
need to be able to do some Unit testing. Any help / tips is greatly
appreciated.
