Issue running minimal example with jss: module java.base does not "opens java.util.jar" to unnamed module

[Phil Eaton]

Hey folks,

I've got a minimal program I'm trying to run:

(require 'abcl-contrib)
(require 'jss)
(setf jss:*muffle-warnings* nil)


(add-to-classpath #P"~/.m2/repository/io/javalin/javalin/3.13.10/")
(jss:jar-import "javalin-3.13.10.jar")


(let* ((port 8080)
       (app (#"start" (#"create" 'Javalin) port)))
  (begin
   (#"get" app (lambda (ctx)
                 (#"result" ctx "Hello World")))))


When I run it:

abcl --batch --noinform --load main.lisp


I get the following exception when requiring jss I think.

jssASDF could not load  because Java exception
'java.lang.reflect.InaccessibleObjectException: Unable to make public
java.lang.String java.util.jar
.JarFile$JarFileEntry.getName() accessible: module java.base does not
"opens java.util.jar" to unnamed module @1ece4432'..

module @1ece4432'.

Any suggestions for getting this (require :jss) working?

Thank you!
Phil
