I'm a newbie trying to use SpotBugs 4.8.3 from the RHEL 8.9 command line and having a fair amount of difficulty. I had to chmod +x /path/to/spotbugs/bin/spotbugs script. Should I have to do that? I would think the script should already be executable when I untar the spotsbug-4.8.3.tgz file.

Regardless, I couldn't get the spotbugs script to work, so I switched to using java to execute the spotgsbug.jar file directly. That at least started the GUI, but I really want to use it from the command line, so I started to investigate the command line options and was surprised to discover -version doesn't return anything.

> java -jar /path/to/spotbugs/lib/spotbugs.jar -version

java -jar /path/to/spotbugs/lib/spotbugs.jar -help works though. The -help output says -version should "print version, check for updates and exit, without running analysis". It doesn't.
