Michael McCandless commented on LUCENE-8043:
--------------------------------------------
Thanks [~simonw]; I love the new assert, and the patch looks correct to me.
I beasted all Lucene tests 33 times and hit this failure, twice:
{noformat}
ant test -Dtestcase=TestIndexWriter -Dtestmethod=testThreadInterruptDeadlock
-Dtests.seed=55197CA38E8C827B
java.lang.AssertionError: pendingNumDocs 0 != 11 totalMaxDoc
at org.apache.lucene.index.IndexWriter.shutdown(IndexWriter.java:1277)
at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1319)
at
org.apache.lucene.index.TestIndexWriter$IndexerThreadInterrupt.run(TestIndexWriter.java:902)
{noformat}
But it does not reproduce for me.
I hit two other unrelated failures; look like Similarity issues ... I'll open
separate issues for those.

> 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)
