[undertow-dev] CLI can add a <host> element without alias attribute (server will not restart after that)

[Wolf-Dieter Fink]

Hi,

not sure whether this should be posted here ...

I've used the current AS8 (upstream) where undertow replace the web 
subsystem.

With the CLI sequence [1] an invalid profile configuration can be added 
and the next server start will stop with an error message [2] because 
the 'alias' must be set.
I think this will be a bug but not sure for which component, I suppose 
the subsystem is responsible to check that, right?
