     I assume `cmd' is a String, and `simDir' and `imageName' are things
that have reasonable toString() methods.  Even so, I cannot imagine how
this would get through a Java compiler, since the only context I can
think of that would make it valid would be to surround it with /*  */.

     Here's a thought: Show us the actual code, not a half-baked
uncompilable paraphrase.  I could make a bunch of guesses about what
your code actually is, and then I could try to debug the code I'd
guessed at -- but the thing you want debugged is your code, not my
guesswork.
