First of all, I assume this is my fault, but I do not know what I screwed up. I am sure I am accidentally leaving out important information, but if you ask me for it I would be happy to include it in a reply.

I am trying to learn about Common Lisp and decided to use ABCL on Windows 10, I ran into this error while going through Xach's tutorial (https://xach.livejournal.com/278047.html).

Specifically, I ran:

(quickproject:make-project "~/src/lisp/swatchblade/"
                             :depends-on '(vecto hunchentoot))

The error I received is:

Error while trying to load definition for system jna from

   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 @6baeb178'.
