>             Project: WildFly Core
>          Issue Type: Bug
>          Components: Server
>    Affects Versions: 10.0.0.Final
>         Environment: * JBoss EAP 7.1/7.2
> * Interface attached to port 0.0.0.0
> * Red Hat Enterprise Linux 7
> * IPv6 disabled in the kernel
>     sysctl -w net.ipv6.conf.all.disable_ipv6=1
>     sysctl -w net.ipv6.conf.default.disable_ipv6=1
> * System properties -Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true

> Error is thrown on startup.

> The customer ships a turn key solution that has the two system properties set: -Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true because they are needed for some cases for customers running IPv6,  but others want to harden their systems by disabling IPv4.
> This works on JBoss EAP 6, but it throws the error on JBoss EAP 7 on the same version of Java.  Furthermore, adding just Djava.net.preferIPv4Stack=false has the same issue, even though it the default value, while leaving it off starts.
> This appears to be related to  controller/src/main/java/org/jboss/as/controller/interfaces/OverallInterfaceCriteria.java#pruneIPTypes where if both properties are null, it leaves the set of candidate addresses alone, but it either are set, it strips out all IPv4 addresses.
