JBIDE-9830 introduced "add and remove" deployment scanners.
By default "remove added" is not enabled.
If I enable "remove added" and then uncheck "add missing" then "remove added" becomes greyed out but it still listed as being enabled.
Saving the server and loading again and the UI still shows this what would be considered illegal state.
That Add missing is disabled, does it ever make sense to remove added ? and if it does why is remove added not enabled.
