[surjitsen]

When running wildfly-swarm as described in section 18.1.4 on Windows 7 with boot docker running on Oracle VirtualBox the following error gets thrown:
ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.undertow.listener.default: org.jboss.msc.service.StartException in service jboss.undertow.listener.default: Could not start http listener

The solution to this problem is to add the following section to the pom.xml:
<plugins>
<plugin>
<groupId>org.wildfly.swarm</groupId>
<artifactId>wildfly-swarm-plugin</artifactId>
<version>${wildfly-swarm-version}</version>
<!-- Add configuration element before executions element -->
<configuration>
<properties>
<java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>
</properties>
</configuration>
<executions>

Thank you so much for sharing this! I tried to add a line in my Dockerfile:
ENV JAVA_OPTS -Xms256m -Xmx512m -Djava.net.preferIPv4Stack=true
but this does not work :/
