graalvm 2022-06-16 | Slack Archive

Can't make Dart->Clojure translator work with graalvm, need help 🙏. Seems like I have problems with reflection:

╰$ ./dartclj "Text('1')"
Exception in thread "main" java.lang.IllegalArgumentException: No matching method substring
 found taking 2 args for class java.lang.String
        at clojure.lang.Reflector.invokeMatchingMethod(Reflector.java:127)
        at clojure.lang.Reflector.invokeInstanceMethod(Reflector.java:102)

Here is a https://github.com/Liverm0r/DartClojure/blob/main/compile.sh file. I pass a flag -H:ReflectionConfigurationFiles with json, where I ask to remain allMethods, constructors, etc. But it doesn't work.

graalvm -v 22.1, java 11

I have also found this @U04V15CAJ https://github.com/borkdude/clj-reflector-graal-java11-fix and tryied to add

{ 
    "name": "java.lang.reflect.AccessibleObject",
    "methods" : [{"name":"canAccess"}]
  },

— didn't work

Read this: https://github.com/clj-easy/graal-docs#reflection

Just add the String class in your reflection config file

borkdude10:06:24

or get rid off your reflection using type hints in Clojure which is even better

borkdude11:06:08

Put #?(:clj (set! *warn-on-reflection* true)) in the top of this file: https://github.com/Liverm0r/DartClojure/blob/7e1a72e2e046725084439be9eb812903f300c042/src/dumch/parse.cljc#L372

borkdude11:06:19

and then it will warn you about the reflective .substring usage

borkdude11:06:26

but you can just use subs there as well btw

Thank you!
