68. SOLR-1468: SolrJ's XML response parsing threw an exception for null
names, such as those produced when facet.missing=true (yonik)
69. SOLR-1471: Fixed issue with calculating missing values for facets in single valued cases in Stats Component.
This is not correctly calculated for the multivalued case. (James Miller, gsingers)
