does native-image handle Java 11 yet?
borkdude 2020-01-31T14:42:34.033500Z
it does
borkdude 2020-01-31T14:43:28.033900Z
@ghadi https://github.com/graalvm/graalvm-ce-builds/releases, you'll need to download one that says java11
borkdude 2020-01-31T14:45:43.035100Z
there is however an issue with clojure + jdk11 when you use Reflector.java. It has a piece of dynamic code that dispatches between 8 and 11 based on some runtime value which confuses the svm analyzer. I worked around that just by copying Reflector.java and removing that dynamic code: https://github.com/borkdude/sci/blob/1294b17d402bfed519289990648cb01c45e8e3a8/reflector/src-java/clojure/lang/Reflector.java#L29-L43

I'm still not using JDK11 for anything GraalVM at the moment, just fyi
borkdude 2020-01-31T14:53:25.036200Z
any specific reason you would want to use jdk11, or just curious?
alexmiller 2020-01-31T14:55:17.036700Z
I'm guessing the new http client :)
ghadi 2020-01-31T14:55:18.036900Z
curious about making stuff with the built in http://java.net.http client
alexmiller 2020-01-31T14:55:23.037200Z
I win!
ghadi 2020-01-31T14:55:35.037500Z
yeah -- gets rid of a bunch of dependencies
borkdude 2020-01-31T14:59:26.038600Z
if you need an http client in a graal binary, you can also use clj-http-lite which has no other dependencies: https://github.com/borkdude/clj-http-lite/blob/fa277d8264b061db8ae9b4fc117b74b1fc2d93ce/project.clj#L7
borkdude 2020-01-31T14:59:40.039100Z
(but it doesn't do async like the JDK11 one I think)
borkdude 2020-01-31T15:00:19.039500Z
it uses HttpURLConnection
borkdude 2020-01-31T15:00:50.039700Z
https://github.com/taylorwood/clojurl also uses clj-http-lite
