Well, it insisted to map "/" on the default servlet (so that 127.0.0.1:8080
was going to my servlet; 127.0.0.1:8080/ was going to the default servlet;
the rest should go to my servlet). I didn't try again wo see if Jasper was
active, but it was still set as a servlet mapping in my context (according
to the logs), which of course isn't that useful.

The code loads the default config before the app config.
Perhaps what we could do when we add a new mapping from the app config is
remove the redundant mappings.

I added a new feature to my custom host as a workaround : it retrieves the
array of children, parses the servlet mappings, and removes anything which
isn't mapped to "/*". I don't need reloading at all on that host, so I think
I should be ok.
