JBoss EAP virtual-servers with same alias names

Issue

We have 2 virtual-servers with the same alias trying to use the root context. It appears that the proxy (mod_cluster) is only registering 1 of the virtual servers and may it be a "first-come-first-server" condition as to which virtual-server gets registered to the proxy and gets the root context.

<subsystem xmlns="urn:jboss:domain:web:2.1" default-virtual-server="default-host" native="false">
    <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
    <virtual-server name="default-host" enable-welcome-root="true">
        <alias name="example.com"/>
    </virtual-server>
    <virtual-server name="default-host2" enable-welcome-root="true">
        <alias name="example.com"/>
    </virtual-server>
</subsystem>
