MP Health reports UP when there is port collision for port 8080

MP Health reports UP when there is port collision for port 8080.

I have simple python app to acquire port 8080 and once it runs I start WF server

import SimpleHTTPServer
import SocketServer

PORT = 8080
Handler = SimpleHTTPServer.SimpleHTTPRequestHandler
httpd = SocketServer.TCPServer(("127.0.0.1", PORT), Handler)

print "serving at port", PORT
httpd.serve_forever()

WF reports Address already in use /127.0.0.1:8080, deployments are not deployed.

Accessing http://localhost:9990/health/ reports "outcome":"UP"
I think this is wrong and DOWN should be reported.

Spec is misleading because it says A producer without health check procedures installed MUST returns positive overall outcome (i.e. HTTP 200) but it silently assumes server started correctly.

I believe authors of the spec expected that if there is some trouble like port collision the server doesn't start, WildFly is a bit further as it allows to boot even if some services are not started properly.
