Re: V3.11.10 Docker uses Java 1.8-282, why not Java 3.11

[Ning Sun]

If I recall correctly, Cassandra 4.0 is the first release to have support for Java 11 and Python 3

https://cassandra.apache.org/doc/latest/new/java11.html

In the document above, the support of JDK 11 is only experimental as of 4.0

Cassandra 4.0 seems to have bumped to Java 11 though

So should we remain on Java 1.8 for Cassandra 3.11.10 ?

This is a link to 3.11.10. where Java 1.8 is used

We are moving to 3.11.10, and we noticed that the Docker image here is based on Java 1.8 – 282 My understanding is that Java 1.8 is no longer (debatable perhaps 😉) , statements suggests that it is no longer supported since Jan-2019 Our company has gone Java 11 since so time back, and it does (ofcourse) come with some improvements on the Mem handling / GC side, and security. https://hub.docker.com/layers/cassandra/library/cassandra/3.11.10/images/sha256-7385bf8ef6333e07b7f56cd5c04e4559ab392afb43a42d14cf838cbb3cee15f3?context=explore <https://hub.docker.com/layers/cassandra/library/cassandra/3.11.10/images/sha256-7385bf8ef6333e07b7f56cd5c04e4559ab392afb43a42d14cf838cbb3cee15f3?context=explore>
