I started looking at this but I think I've gone as far as I can
without some advice.  I started by modifying JettyModuleBuilder to
create the servlet gbeans in the order specified by the
load-on-startup elements, and that worked the first time I ran the
server.  But not the second time.  So I looked into it a little more
and found that the BasicDependencyManager stores the dependencies as a
set, so when GBeanInstanceState.startRecursive() gets the children (in
this case the servlets) to start there's no order to them.  

So I'm at a loss for what to do.  Modifying the dependency manager to
use lists instead of sets seems pretty drastic (since some of the
methods return sets) but it would probably make the server start up
more predictably.  But I'm not sure that's enough to ensure that the
load-on-startup order is respected all the way through deployment and
startup.

If anyone has any ideas I'd be happy to put some more legwork into
this.

Thanks,
Toby

PS.  Ordinarily I'd add comments like this to Jira but it's down:
