More notes on class initialization
See original GitHub issuehttps://github.com/lread/clj-graal-docs#class-initialization
See https://github.com/oracle/graal/discussions/3476
From Graal 22 on, the global --initialize-at-build-time
option will be deprecated.
It is possible to get a list of Clojure-produced packages with something like:
(require 'babashka.main)
(->> (map ns-name (all-ns)) (remove #(str/starts-with? % "clojure")) (map #(str/split (str %) #"\.")) (keep butlast) (map #(str/join "." %)) distinct (map munge) (cons "clojure"))
and then make a comma separated list out of that:
"--initialize-at-build-time=clojure,sci.impl,selmer,babashka.nrepl,babashka.impl.clojure.java,babashka.impl,rewrite_clj.node,bencode,rewrite_clj.parser,babashka.impl.clojure,org.httpkit,rewrite_clj.custom_zipper,rewrite_clj.zip,borkdude.graal,babashka.nrepl.impl,babashka.pods,cognitect,babashka,edamame.impl,cheshire,rewrite_clj,hiccup,sci,borkdude,flatland.ordered,babashka.pods.impl,clj_yaml,babashka.impl.clojure.core,datascript,hf.depstar,babashka.impl.tools,sci.addons,babashka.impl.clojure.test"
This has an additional benefit that not all Java classes are initialized at build time, reducing the chance on any incorrect behavior.
