    Description

      In solr 4.0 there is log4j-over-slf4j.

      But if you have log4j jars also in the classpath (e.g. contrib/extraction, contrib/clustering) you can get strange errors such as:
      java.lang.NoSuchMethodError: org.apache.log4j.Logger.setAdditivity(Z)V

      So I think we should remove the log4j jars in these contribs, all tests pass with them removed.
