    org.apache.commons.logging is Implicit Dependency now?

      From https://docs.jboss.org/author/display/AS7/Developer+Guide#DeveloperGuide-ApacheCommonsLogging :

      To avoid a ClassNotFoundException, you will need to add a dependency for the module that contains those classes. The module name for Apache Commons Logging is "org.apache.commons.logging", so your MANIFEST.MF file will look like this:

      Dependencies: org.apache.commons.logging 

       

      And this is what I had to do before 7.1.0. But when I try a simple application with Apache Commons Logging (which is not packaged) in jboss-as-7.1.1.Final it works without adding dependencies. With tracing enabled I see:

       

       

       

      {code}

      {code}

       

       

      Also log4j seems to be added automatically. This would contradict the tabel in https://docs.jboss.org/author/display/AS7/Implicit+module+dependencies+for+deployments as well?
