        ./add-user.sh -a -u ejb -p 1234
      • Package the attached sample application: 
        unzip hello-world-ejb-issue.zip
cd wildfly-http-client
mvn clean package
      • Deploy resulting hello-world-ejb-issue.war into the server.
      • Access the URL: http://127.0.0.1:8080/hello-world-ejb-issue?exception=true&conn=http
      • A ClassNotFoundException is thrown instead of the custom HelloWorldException.
      • For example if the exception is not generated exception=false or remoting is used conn=remoting the issue does not happen.
