We are planning to upgrade our Cassandra servers from 3.0.11 to 4.0.1 Here it says to use JDK 8. I would like to know if as of this writing this is still the case. I believe the latest released Oracle version is JDK 17.


The primary version for Cassandra 4.0 is Java 8. The Java 11 is marked as experimental, but there was a recent discussion of removing that label for 4.0.

But work on the Java 17 has started only recently, and it may not be supported for 4.0, but for newer major releases

  • Okay. So for a production environment you would recommend we use Java 8?

    Most probably. Although look into mailing list, there were some people saying that they are using Java 11 in prod

  • Yes, seems like many support making 11 "non experimental"
