Using Ubuntu 16.04 LTS + ES 6.0.1 + OpenJDK9, simple basic config. The service crashes:

Is Java 9 supported nowadays with 6.x https://dzone.com/articles/java-9-elasticsearch-benchmark? Or still good old 8 only?

Please let me know if you need more info.

Thanks!

Java9 is not supported. You need to use Java8 instead.

3

Are there plans to support 9?

Perhaps good to update https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html which says "Elasticsearch requires at least Java 8.". I guess 9 is at least 8 and others might make the same mistake.
