+1 Actually, there is also a proposal to stop supporting JDK 8 in Flink, and the flink-kubernetes-operator also requires JDK 11. Considering the future functionality and long-term development, upgrading the JDK version is very necessary. Currently, Scala is simultaneously maintaining two versions: 2.11 and 2.12, which causes problems for project release and maintenance. I agree to upgrade both JDK and Scala.
