My guess is you have an antivirus software that is corrupting or blocking one of the OSGI bundle jars that Lucee is trying to load. Of course, the error doesn't tell us which one, so it's hard to say. You could check the Lucee bundles folder in your CommandBox home and see if any of them look invalid or 0k or something. The bundled folder is located here
C:\Users\you\.CommandBox\engine\cfml\cli\lucee-server\bundles
Not much CommandBox itself can do about this. The actual error is coming from the JDK which is called by Lucee which is bundled by CommandBox.
In fact, there's the line of the Lucee source code that's failing:
You can see, it's just:
JarFile jf = new JarFile(jar);
The jar file is either corrupt or being blocked at the file system. If you really care to find out the issue, you could compile a custom lucee.jar where you add in some debugging code that logs the path to the jar file in question before it's loaded. Then at least you'd know which jar is having the issue. All you'd need would be to System.println( jars[i].toString() ) right here
Let me know if you want me to make a jar for you to try with this debugging code in it.
Thanks!
