I have been working with Elasticsearch as a developer for a couple of years now and have successfully written some NiFi services that use the now deprecated Java API that uses port 9300 to query/retrieve/delete records to/from elasticsearch. I am currently undergoing an effort to migrate to the most recent elasticsearch-java API 8.5.3 which uses port 9200. The associated jar file depends on httpclient. In my pom.xml file, I am specifying httpclient 4.5.13 as I have seen some other traffic on the internet ([spring boot - elasticsearch java.lang.NoSuchMethodError: org.apache.http.client.utils.URLEncodedUtils.formatSegments - Stack Overflow](https://stackoverflow.com/questions/71725325/elasticsearch-java-lang-nosuchmethoderror-org-apache-http-client-utils-urlencod)) stating version 4.5.13 solves their problem that is very similar to the one I am experiencing.

Does anyone know the correct minimum version of httpclient that the Java API 8.5.3 requires to run properly?

Here is the relevant stack trace that I am experiencing:

```auto
java.lang.NoSuchMethodError: 'java.lang.String org.apache.http.client.utils.URLEncodedUtils.formatSegments(java.lang.String[])'

As per

> httpclient:4.5.10

@swallez might know more.
