Hi Laurent Iceberg is built with Java 8 due to dependency like Spark versions, it will update to Java 11 soon.
That was my concern about jumping directly to Java 17: projects using Arrow might need time. I think it's more secure to go to Java 11 as an intermediate step. About JPMS, I'm not convinced it's worth the effort regarding the gain (I don't know a lot of projects using JPMS). So, I would go to Java 11 for now.
