Unable to disable iiop port (non-ssl)

Wildfly 13.0.0.Final

Removing the "iiop" socket-binding from the orb configuration:

<subsystem xmlns="urn:jboss:domain:iiop-openjdk:2.0">
<orb ssl-socket-binding="iiop-ssl"/>
<initializers security="identity" transactions="spec"/>
<security server-requires-ssl="true" client-requires-ssl="true" support-ssl="true" security-domain="jsse"/>
</subsystem>

and commenting out the iiop socket-binding leads to the following error:
