that's already there ;) an index is appended to the domain name, if the
domain is already registered(same as you suggested, only that first
domain won't have any index).
Phaps I can drop the warning (replace with trace), but I still might
want people to know that there is a name conflict : e.g. they might
lookup the cache in JMX programmatically and work with a totally
different cache instance..
