+1 to dropping Java 17 support in Spark 5.0.0. -1 to dropping Java 21 support. As Xiao mentioned, downstream projects (e.g., Iceberg) and users on Spark 4.x would lack a clear upgrade path without Java 21 support. Additionally, I suggest we start a separate discussion thread to gather more feedback from the community.
