Fail to start jax-rs service on wildfly-swarm

Question

I have a JAX-RS service that works locally with wildfly-swarm 1.0.0.Beta8, but when I boot it on a remote machine, I get the following exception:

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

    at org.wildfly.extension.undertow.ListenerService.start(ListenerService.java:138)
    ... 5 more

Also when I deploy the app to a full wildfly 10, it works just fine.

I googled that the 'Protocol family unavailable' exception can be related to a machine having only an IPv6 address while java defaults to IPv4, but this machine does have an IPv4 address.

I have no idea what I might be doing wrong.

Any suggestions?

Can you try modifying the wildfly-swarm-plugin to have a setup like:

  <plugin>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>wildfly-swarm-plugin</artifactId>
    <configuration>
      <mainClass>org.wildfly.swarm.examples.netflix.ribbon.frontend.Main</mainClass>
      <properties>
        <java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>
      </properties>
    </configuration>
    <executions>
      <execution>
        <goals>
          <goal>package</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

It may need the java.net.preferIPv4Stack set to true.

I build upon Ken's answer. When I tried it I had the following error: java.lang.ClassNotFoundException: org.wildfly.swarm.examples.netflix.ribbon.frontend.Main.

Removing the <mainClass> element from the plugin configuration in the pom worked like a charm.

    <configuration>
      <properties>
        <java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>
      </properties>
    </configuration>

Add a java option in $JBOSS_HOME/bin/standalone.conf JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true"
