> 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
> stack trace:
