Okay - not sure why Outrigger is suffering this exception at the

Right well httpmd is all about integrity, not really about class
evolution.  You could just generate a digest and tag that to the end of
the .jar name and get the same effects without needing to install httpmd.

Ah, well if you just post the name of the script you're using, that's
sufficient.

Hmm, wouldn't say there was a solid reason.  But there might well be
some lore around not frightening the user with lots of command-line bits
to wade through for security options they aren't using and are maybe
very scared of.

Okay, well I'd say httpmd is probably not the right tool for this job.
