> The IndexWriter check for too many documents does not always work, resulting in going
over the limit.  Once this happens, Lucene refuses to open the index and throws a CorruptIndexException:
Too many documents.
> This appears to affect all versions of Lucene/Solr (the check was first implemented in
LUCENE-5843 in v4.9.1/4.10 and we've seen this manifest in 4.10)
