Section: 3.2. JacORB Subsystem Configuration Changes

The migration guide refers in text to jacorb susbystem in version 2.0

The urn:jboss:domain:jacorb:2.0 subsystem configuration namespace in the server configuration file has been replaced by the urn:jboss:domain:iiop-openjdk:1.0 namespace.

JBoss EAP6 does uses jacorb subsystem in version 1.4. Please change urn:jboss:domain:jacorb:2.0 to urn:jboss:domain:jacorb:1.4.

Note: the subsystem in version 2.0 is used in WFLY9 but it is not productized version. EAP6 as productized version of app server uses 1.4.
