Hi, All. Thank you for your attention!
UPDATE: We succeeded to build with JDK8 and test with JDK11. - https://github.com/apache/spark/pull/25587 - https://amplab.cs.berkeley.edu/jenkins/job/NewSparkPullRequestBuilder/4842 (Scala/Java/Python/R) We are ready to release Maven artifacts as a single artifact for both JDK8 and JDK11. According to this email thread, I believe this is the last piece to resolve the following issue. https://issues.apache.org/jira/browse/SPARK-24417 (Build and Run Spark on JDK11) To committers, please use `[test-hadoop3.2][test-java11]` to verify JDK11 compatibility on the relevant PRs. Bests, Dongjoon.
