Umm, looks strange.
How recent is you checkout?  I don't think merlin.sh takes the run 
argument as a parameter.  There was some recent updating of the *.sh 
scripts.  The run functionality is under merlin-server.sh whereas 
merlin.sh is simple command line deployment.  Thing that I'm confused 
about is that you should be getting an illegal cli option error message.

The merlin-bootstrap-1.0.jar jar handles the bootstrapping of 
classloaders - one of the classloaders holds the ExceptionHelper class 
(you can see details of the jar files that are loaded by looking in the 
bootstrap har file merlin.properties resource.

Nah  - I know its working on that "other" os because Alexis was playing 
with a fresh CVS version earlier today.
Could you do me a favour and confirm that the CVS checkout is up-to-date.
