Hi [~shinichiro abe], what version of Solr are you using?
The ManifoldCF version of Solrj was updated to 7.4, and this caused many problems.  I think
it may the case that solrj 7.4 is incompatible with previous versions of Solr before 7.4.
 I have already modified ModifiedHttpClient to work with SolrJ 7.4.

The code committed to trunk uses unchanged SolrJ 7.4 transmission for all UpdateRequests,
like delete requests or commit requests.  Only for ContentStreamUpdateRequests does it modify
how documents are sent to use multipart HTTP form post.  We could try the following to be
sure this is written correctly:

(1) Try using trunk ManifoldCF against Solr 7.4 and see if it works for delete requests.
(2) If that fails, try changing line 291 of HttpPoster.java to do "new HttpSolrClient" instead
of "new ModifiedHttpSolrClient".  That should be using an unchanged SolrJ 7.4 then.

Please let me know what you find.

> The "r69acbd9 - Fix solr connector content deletion bug" has introduced another bug :

> It is now impossible to ingest documents into Solr 7.4.0, we obtain the following error
: Error from server at http://localhost:8983/solr/FileShare: missing content stream
> The fact is, the requestWriter.getContentWriter(request) object is equal to null only
on commit requests. So the new lines of code introduced by the fix, which are based on the
test of this object, result in a null Collection<ContentStream> streams object and
so the update request is failing.
> Concerned class : org.apache.manifoldcf.agents.output.solr.ModifiedHttpSolrClient
