    Description

      (Hopefully this belongs to WildFly Core. If not, please move to WildFly.)

      I'm doing a programmatic invocation of a simple mgmt operation on the root mgmt resource, say e.g. :whoami. I'm doing this against a freshly built WildFly from master branch (commit e2b9ecfb) and on the client side, I'm depending on org.wildfly.core:wildfly-controller-client:1.0.0.Alpha4.

      The code looks like this:

      ModelControllerClient client = ModelControllerClient.Factory.create("localhost", 9990);
      
      try {
          ModelNode op = new ModelNode();
          op.get(ClientConstants.OP).set("whoami");
          op.get(ClientConstants.OP_ADDR).set("");
          ModelNode result = client.execute(op);
          System.out.println(result);
      } finally {
          client.close();
      }
      

      This fails with an exception like this:

      Exception in thread "main" java.io.IOException: java.util.concurrent.ExecutionException: Operation failed

      However, when I remove the line that sets address (op.get(ClientConstants.OP_ADDR).set("");), it works just fine.

      Fine, I made a mistake, but getting an EOFException? That's hardly an appropriate response. I should get a proper failure ("outcome" => "failed" etc.).
