Noble Paul commented on SOLR-1769:
----------------------------------


Let me assume that you are using the 1.4 release and not a daily nightly build

I don't see anything obviously wrong. meanwhile, why don't you just pick up the 
solrconfig.xml from 1.4 and make the necessary changes and test it out?
