Hello @shoebsayyed118 ,

welcome to our forum.

For version compatibility of ES with Java, please look here:

Support Matrix

From what I found, the preview of Optimize bundled with ES comes with ES version 7.16.2 which is not compatible with Java 18 but with Java 1.8, 11 and 17.

Please not that Optimize is not compatible with Java 1.8, so I would suggest you go for Java 17.

Depending on the OS of your local machine, there are tools to manage multiple Java versions at the same time (like jenv).

I hope this helps

Jonathan
