Hi Laurent, Kudos again for doing the migration from Java 8 -> 11 in Arrow. That was a large contribution, thank you!
I see a few reasons to drop Java 11: - Java 11 official support ended September 2023, but it will receive extended support until 2032. - Dependencies are upgrading at a faster pace. For example, ORC v2.0 supports Java 17+.
