Multiple values in solrconfig.xml cause error with solr 4.5+

I'm cross pointing this issue since it effects the solrconfig.xml. I couldn't get my Tomcat7 Solr 4.7 working until even though I copied over the necessary files. After finding this post here #2107417 and removing the duplicate entries in the solrconfig.xml all was well.

XML configuration parsing is now more strict about situations where a single setting is allowed but multiple values are found. In the past, one value would be chosen arbitrarily and silently. Starting with 4.5, configuration parsing will fail with an error in situations like this. If you see error messages such as "solrconfig.xml contains more than one value for config path: XXXXX" or "Found Z configuration sections when at most 1 is allowed matching expression: XXXXX" check your solrconfig.xml file for multiple occurrences of XXXXX and delete the ones that you do not wish to use. See SOLR-4953 & SOLR-5108 for more details.

The following settings are multiple but should be a single (and cause errors in solr 4.5+)

useCompoundFile
ramBufferSizeMB
mergeFactor

Note: I found this similiar issue and after patching the solrconfig.xml it works like a gem!
