this issue appears when visone 2.19 or older is run on JDK 16 on Mac OS X.
The workaround is to make sure visone is executed on an older JDK. I don't know about JDKs 9 to 15, but I'm sure it runs on an up-to-date JDK 8.
So first, one has to install an older JDK. If as a result multiple JDK versions are installed on the same Mac, one can use the java_home command line utility to choose a specific JDK version. I think this should be the command for running it on JDK 8 from the terminal (when visone-2.19.jar is in the current directory):
java_home -v 1.8 --exec java -jar visone-2.19.jar
I plan to include a fix for this problem in the 2.20 release of visone.
