According to https://archive.apache.org/dist/spark/docs/3.5.0/#downloading

Spark runs on Java 8/11/17, Scala 2.12/2.13, Python 3.8+, and R 3.5+. Java 8 prior to version 8u371 support is deprecated as of Spark 3.5.0. When using the Scala API, it is necessary for applications to use the same version of Scala that Spark was compiled for. For example, when using Scala 2.13, use Spark compiled for 2.13, and compile code/applications for Scala 2.13 as well.

Therefore the minimum JDK 17 is starting only from Spark 4. This ticket should be tied to Spark 3.5 support deprecation
