I'd like to move from commons-logging to slf4j, primarily to avoid classloading issues for our users, and it also supports MDC (Mapped Diagnostic Context):
http://www.slf4j.org/ Here's what prompted my investigation: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2696 Hibernate has moved over already, and many Apache projects have done so as well. Any objections?
