The CONFIG message from JBoss to apache is always formatted like the following and still uses the resolved ip address instead of the bound to host name:
Port=8009, Host=127.0.0.1, Type=ajp, StickySessionForce=No, Maxattempts=1
Even if the Connector is defined like:
<Connector port="8009" address= "localhost" protocol="AJP/1.3" redirectPort="8443" />
