>             Project: WildFly
>          Issue Type: Bug
>          Components: Web (Undertow)
>    Affects Versions: 14.0.1.Final, 12.0.0.Final, 13.0.0.Final

> Undertow server needs default-host to be set to be able to be used as Undertow subsystem default-server otherwise Wildfly would not start due to:
> {code}
> ERROR [org.jboss.as.controller] (Controller Boot Thread) WFLYCTL0362: Capabilities required by resource '/subsystem=undertow' are not available:
>     org.wildfly.undertow.host.test-server.default-host; Possible registration points for this capability: 
> 		/subsystem=undertow/server=*/host=*
> {code}
> This is dangerous as after calling a {{reload}} operation, the server simply fails and crashes. One can accidentaly kill the server with this and \!manual\! fix is necessary to the configuration to be able to start server again.
> I think that there should be some check that configuration of the newly created server is complete and valid before it is set as a default server.
