Description

I'm enabling <statsCache class="org.apache.solr.search.stats.ExactSharedStatsCache"/> at the simple SolrCloud setup and got:

Caused by: org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://...:8983/solr/V..._shard2_replica2: java.lang.NullPointerException

Is there any clue? It seems like swithing to LRUStatsCache helps, but why so?
