-------------------------------------------
Hi [~kwri...@metacarta.com] [~julienFL] ,
I’ve tried to modified the source code for using Zookeeper `3.5.6` and
migrating Java from 8 to `11`, and the test run-tests-framework was OK.
Attached the patch [^CONNECTORS-1740.patch] I used in my test.
Also, I tried various other Zookeeper versions(3.6.2, 3.7.0, 3.7.2, 3.8.0,
3.8.1), but all of them failed in the test run-tests-framework due to an error
as below.
```

> Project: ManifoldCF
> Issue Type: Improvement
> Components: Lucene/SOLR connector
> Affects Versions: ManifoldCF 2.23

> Assignee: Julien Massiera
> Priority: Major
> Attachments: CONNECTORS-1740.patch

>
> The current Solr output connector is not compatible with Solr 9.x
> We need to update the connector with SolrJ 9 and make sure that the custom
> code (multipart post requests, basic/preemptive auth) is still required, and,
> in case it is, port it !
