As of JBoss EAP 7.1.0.CR1, the EJB interceptor in app-client quickstart returns a slightly different message to the one expected by readme file:

ClientContext is here = {Client =dev84, jboss.source-address=localhost/127.0.0.1:45315}

Both of the mentions of the server.log message need to be upgraded in the readme file. The occurences are step 4 of Access the Remote Client Application from the Same Machine and step 9 of Configure Machine_2 (Local Client Machine).
