*** MyNameService.lookupAllHostAddr called

      "*** MyNameService.lookupAllHostAddr called" is printed in stdout if the custom NameService has been enabled.

      On WildFly, define a system property in standalone.conf:

         JAVA_OPTS="$JAVA_OPTS -Dsun.net.spi.nameservice.provider.1=dns,MyNameService"

      And prepend the new module path in standalone.sh:

          JBOSS_MODULEPATH="/path/to/nameserviceProviderTest/modules:$JBOSS_HOME/modules"

      Then deploy the testweb.war in the archive and access http://localhost:8080/testweb/test.jsp. The message is not printed in stdout.

      System property sun.net.spi.nameservice.provider.<n> allows a user to customize a NameService. It works on a standalone java, which is using JBoss Modules, if services="import" is added on sun.jdk module dependency and the sun.jdk module has the following additional dependencies.

                      <path name="sun/net/spi/nameservice"/>
                <path name="sun/net/spi/nameservice/dns"/>

      Though it doesn't work as a web application which has the same module path and the same dependency in jboss-deployment-structure.xml.
