Version-Release number of selected component (if applicable):
- JBoss ON 3.2.3
- Application Platform Plugin Pack Update-01 for JBoss ON 3.2 

How reproducible:
Not sure.

Steps to Reproduce:
1. 
2.
3.

Actual results:
Host Controller is properly discovered but it's availability is down

Expected results:
Host Controller is properly discovered and it's availability is up

Additional info:
host-slave.xml file will be additionally attached

Above error shows that exception happens when trying to get name parameter (see plugins/jboss-as-7/src/main/java/org/rhq/modules/plugins/jbossas7/BaseServerComponent.java):

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

So, line  "107 return new PROPERTY_VALUE(pair[0], pair[1]);" fails because there is no pair[1], but only pair[0].
