             Summary: EOFException when adding empty address to a mgmt operation
                 Key: WFCORE-48
                 URL: https://issues.jboss.org/browse/WFCORE-48
             Project: WildFly Core
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Domain Management
            Reporter: Ladislav Thon
            Assignee: Brian Stansberry


(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:

{code:java}
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();
}
{code}

This fails with an exception like this:

{code}

{code}

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.).
