Facing the same issue. Any work around?

This from three years ago, so I don't know whether I ever fixed it. If you haven't tried that yet, make sure to run on Java 11 with all dependencies up to date. If the problem persists (har har), open a question on StackOverflow. You can leave the link here and I may take a look if I have time.
