Hello, I'm running into this error: Could not initialize class org.lmdbjava.ByteBufferProxy on linux: Clojure CLI version 1.11.1.1113 openjdk 17.0.4 2022-07-19 whilst attempting to recreate the examples in the readme. Following issue: https://github.com/juji-io/datalevin/issues/73 , I added the following the jvm-opts to deps.edn without success. deps.edn 

{:paths ["src"]
 :deps {ring/ring {:mvn/version "1.9.5"}
        datalevin/datalevin {:mvn/version "0.6.17"}
        rum/rum   {:mvn/version "0.12.9" :exclusions
                   [cljsjs/react cljsjs/react-dom]}}
 :jvm/base {:jvm-opts ["-J--add-opens=java.base/java.nio=ALL-UNNAMED"
                       "-J--add-opens=java.base/sun.nio.ch=ALL-UNNAMED"]}}

I am not an expert on deps.edn, but my hunch is that you are adding jvm-opts at the wrong place. Could you try to add it under deps? Or ask in clojure channel how to do that.

For future reference, I updated the comment in github according to alex miller’s answer. https://github.com/juji-io/datalevin/issues/73#issuecomment-1242560698
