If a client use WildFlyInitialContext without properties the following Exception is thrown:
Exception in thread "main" javax.naming.NoInitialContextException
at org.wildfly.naming.client.WildFlyInitialContext.getDefaultInitCtx(WildFlyInitialContext.java:65)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:350)
at javax.naming.InitialContext.lookup(InitialContext.java:417)
at org.jboss.wfink.eap71.playground.wildfly.client.WildFlyICConfigClient.main(WildFlyICConfigClient.java:33)

It is expected that this works according to https://github.com/wildfly/wildfly-naming-client#usage.
