I just need a reference to this service as it contains config information that is stored in the subsystem (standalone.xml, sorry if I'm confusing the terminology). Don't care where or when the Undertow Handler gets this referenc(deploy time or runtime).
Is it possible to create HttpHandler instances in a deployment processor and attach them to the WAR deployment? What about AuthMechanisms? I guess I should dive into the undertow subsystem a bit more.
