Description of problem:
Adding http-interface in the host controller's host-slave.xml is not recognised by RHQ Agent causing Host Controller's availability to stay DOWN. The agent.log file shows the following WARN message:
*********************************************************

*********************************************************

Version-Release number of selected component (if applicable):
RHQ 4.9.0

How reproducible:
Always

Steps to Reproduce:
1. EAP (6.2 in this case) started in domain mode where Domain Controller (DC) is running on one machine and Host Controller (HC) on another machine;

2. HC started using host-slave.xml file or host.xml but without http-inteface defined so it looked like:
********************************************
...
<management-interfaces>
    <native-interface security-realm="ManagementRealm">
        <socket interface="management" port="${jboss.management.native.port:9999}"/>
    </native-interface>
</management-interfaces>
...
********************************************

3. Both DC and HC are discovered and imported in the RHQ Server inventory;

4. DC is available while HC is DOWN;

5. Edit host-slave.xml or host.xml file to add http-interface in the following way so host-slave.xml/host.xml should contain:
*********************************************
...
<management-interfaces>
    <native-interface security-realm="ManagementRealm">
        <socket interface="management" port="${jboss.management.native.port:9999}"/>
    </native-interface>
    <http-interface security-realm="ManagementRealm">
        <socket interface="management" port="${jboss.management.http.port:9990}"/>
    </http-interface> 
</management-interfaces>
...
*********************************************

6. Saved host-slave.xml/host.xml file and restarted the host controller (HC);

7. Restarted the RHQ Agent;


Actual results:
Change made in host-slave.xml/host.xml is not recognised so HC is still Down in RHQ Server inventory and WARN message is logged in the agent.log file.


Expected results:
Availability of HC is changed to UP and no exception is logged in the agent.log file. 

Additional info:

To work around this:


 * remove (uninventory) unavailable host controller from the RHQ inventory;
 * let RHQ Agent on the machine 2 to discover HC again;
 * inventory discovered Host Controller again;
 * make sure that the username/password is set correctly in the host controller Connection Settings page;
 * execute "Execute Availability Scan" operation for RHQ Agent resource on the machine 2.
