I saw similar topics but all was about quite old version of Graylog.
We plan new installation of Graylog (we also plan install Elasticsearch on the same machine).
Few days ago Elastic released Elasticsearch 6.6 which supports Java 11.
In Graylog documentation I can see latest supported version is Java 8 (I suspect documentation was writed where elastic also support only java 8) .
On Oracle webpage is information
Java SE 8 is going through the End of Public Updates process (…) until at least the end of December 2020 for Personal Users, and January 2019 for Commercial Users
Because it is new installation we thing about install newest components.
Could you tell me what is last officially supported (by Graylog 2.5) version of Java?
