Scala 2.11 is EOL, and only Scala 2.12 will support JDK 11 https://github.com/scala/scala-dev/issues/559#issuecomment-436160166 <https://github.com/scala/scala-dev/issues/559#issuecomment-436160166> , we might need to make Scala 2.12 as default version in Spark 3.0 to move forward.
Given Oracle's new 6-month release model, I think the only realistic option is to only support and test LTS JDK. I'll send out two separate emails to dev to facilitate the discussion.
