Why would a command ever fail?

In understanding, a command can only fail if there's a programming  
error in JOSM. Even so it is, of course, a good thing to handle that  
gracefully rather than just throw an exception. - But are your  
patches introducing commands that may fail for other reasons than  
programming errors?
