*Hi!*
*Should we support both JDK-11 & JDK-8?* IMO absolutely yes, let's not break up with JDK-8: according to its lifecycle, it's going to stay with us for a long time. I believe a) we should be able to compile on JDK8, JDK11, and JDK17 (github actions can cover this conveniently in precommit time, like tez <https://github.com/apache/tez/blob/master/.github/workflows/build.yml>) b) the release artifacts should be compatible with JDK8 as long as it is with us.
