> Hello,
> I am getting a NPE when using the TermVectorComponent in combinition with
> ExactStatsCache.
> I am using SOLR 5.3.0 with 4 shards in total.
> I set up my solrconfig.xml as described in these 2 links:
> TermVectorComponent:
> https://cwiki.apache.org/confluence/display/solr/The+Term+Vector+Component
> ExactStatsCache:
> https://cwiki.apache.org/confluence/display/solr/Distributed+Requests#Configuring+statsCache+implementation
> My snippets from solrconfig.xml:
> {code}

> Stats Cache

> <statsCache class="org.apache.solr.search.stats.ExactStatsCache"/>

> Unfortunately a request to SOLR like
> "http://host/solr/corename/tvrh?q=site_url_id:74"; ends up with this NPE:
