      Description

      It happens when there is a string field with docValues="true" and default="".
      Then, with documents that have empty string value in the field,
      values.exists(docID) is true but values.strVal(docID) is null, and it throws null pointer exception when trying to add the value to distinctValues set.
      the solr query is stats=true&stats.field=X&stats.calcdistinct=true
