When bundling logback-classic-0.9.17 in a web application, the following is reported during startup:

2009-11-30 16:11:26,000 ERROR [STDERR] (main) SLF4J: Class path contains multiple SLF4J bindings.

We need access to logback APIs because we configure logging on the fly (change log levels without restarting the app)
