Description

On our project we're using directly logback to start up a custom mbean to be able to change log levels dynamically, among other things. Most of these operations are Logback-specific, they're not available via SLF4J API

For testing we use Jetty, so when we're doing an mvn jetty:run, the mbean gets init'd and we get an Exception stating "ClassCastException: org.slf4j.impl.SimpleLoggerFactory cannot be cast to ch.qos.logback.classic.LoggerContext", due to slf4j-simple being on maven's lib. This is very likely to happen with other container plugins (tomcat7 et al)
