- The documentation does not seem to document the minimum JDK runtime requirement for `org.elasticsearch.plugin:x-pack-sql-jdbc`.
- I am of course aware that using the JDBC driver requires a trial or paid license for the Elasticsearch cluster, and that the JDBC driver `org.elasticsearch.plugin:x-pack-sql-jdbc` itself is not an OSS license. I mainly want to test the PR [[FLINK-30702] Add Elasticsearch dialect by grzegorz8 · Pull Request #136 · apache/flink-connector-jdbc · GitHub](https://github.com/apache/flink-connector-jdbc/pull/136) on the Apache Flink side locally.
- But [SQL JDBC | Elasticsearch Guide [8.17] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/sql-jdbc.html) does not seem to record the minimum JDK version requirement for `org.elasticsearch.plugin:x-pack-sql-jdbc`.
- I want to know whether the minimum JDK version requirement for `org.elasticsearch.plugin:x-pack-sql-jdbc` is JDK 8, or JDK23 consistent with Elasticsearch Server? I'm referring to [Update bundled jdk to 23 by rjernst · Pull Request #114823 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/pull/114823) .

I don't understand. The plugin runs inside Elasticsearch so it uses the JVM provided by Elasticsearch.  
It's not meant to be reused anywhere else.

- I am surprised that the usage of `org.elasticsearch.plugin:x-pack-sql-jdbc` is mainly for Elasticsearch internals, even though the module is documented. I will sync this idea to [[FLINK-30702] Add Elasticsearch dialect by grzegorz8 · Pull Request #136 · apache/flink-connector-jdbc · GitHub](https://github.com/apache/flink-connector-jdbc/pull/136) .

Oh! I thought it was an internal plugin jar but actually no.  
Forget about what I wrote earlier on. I was wrong.
