[jira] [Commented] (FLINK-10725) Support for Java 11 (LTS)

    [ https://issues.apache.org/jira/browse/FLINK-10725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16841579#comment-16841579 ] 

Eron Wright  commented on FLINK-10725:
--------------------------------------

Want to mention an interesting detail, JDK10 introduced the `UseContainerSupport` flag which is said to improve on the experimental containerization flags that were in JDK9.   Considering that Flink makes significant use of off-heap memory (e.g. rocksdb) and is typically deployed into a container environment, full support for JDK10/11 may significantly improve usability and stability.

> Java 8 is over 5 years old and will be end of life in 2019/2020. Java 11, the latest long-term support release, became GA in September 2018. Given that FLINK-8033 still hasn't been resolved and that Java 9 was end of life (discontinued / no longer publically available or supported) since March 2018, it doesn't make sense to continue trying to add Java 9 support when both Java 9 and Java 10 are end-of-life.
