> There are a few classes that directly rely on log4j to be on the classpath instead and don't use the slf4j logging facade. This creates problems when trying to switch the logging implementation. 
> 1. org.apache.solr.core.ZkContainer
> https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/java/org/apache/solr/core/ZkContainer.java#L218
> I don't know the impact of this change, but shouldn't this call `org.apache.solr.logging.MDCLoggingContext.clear()` ?
> 2. org.apache.solr.handler.component.RangeFacetProcessor and org.apache.solr.handler.component.RangeFacetRequest
> should use slf4j instead of log4j
> I had a stab at it at
