The same situation is with every shipped and supported configuration/profile. As base for my explanation I'm using standalone.xml. Standalone.xml declares xmlns as:

<server xmlns="urn:jboss:domain:1.3">

The real XSD file which defined elements is jboss-eap-6.0/docs/schema/jboss-as-config_1_3.xsd.

The very common Linux system has implemented and enabled dualstack in these days. If we instruct AS instance to bind to any IPv4 address via

<interface name="public">
    <any-ipv4-address />
</interface>

The real result is to bind running AS instance to any IP address, not only in IPv4 address space but in IPv6 too!

With default setting (= -Djava.net.preferIPv4Stack=true), result is correct - it is bound to ANY IPv4 addresses only.
