Problem with exporting project with linked JAR in Eclipse

Hi, I'm having the same issue.
I originally copied the files directly into my project, which was unable to run. I then read this thread and downloaded the v0.8 jar which works when running in Eclipse, but the exported runnable JAR fails with the following message:
WARNING: An illegal reflective access operation has occurred

It seems to be the same as when I tried copying my project files into the JXInput folder imported as a Maven project, then exported the whole thing as a runnable JAR. I'm not sure if this is the right place to post this sort of issue, but is there any way I can get the linked JAR to work? Thanks!
What JDK version are you using? This might be a new policy which will make it harder to load the library on newer versions.
Seems like there are a new set of restrictions on setAccessible on Java 9+, which was used with a hack to load the native libraries. The hack is not needed with System.load(String)
