EOFException when address of a mgmt operation is of a bad data type ------------------------------------------------------------------- Key: WFCORE-48 URL: https://issues.jboss.org/browse/WFCORE-48 Project: WildFly Core Issue Type: Bug Components: Domain Management Reporter: Ladislav Thon Assignee: Emmanuel Hugonnet (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} Exception in thread "main" java.io.IOException: java.util.concurrent.ExecutionException: Operation failed at org.jboss.as.controller.client.impl.AbstractModelControllerClient.executeForResult(AbstractModelControllerClient.java:129) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.execute(AbstractModelControllerClient.java:71) at cz.ladicek.wildfly.ErrorReproducer.main(ErrorReproducer.java:17) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:134) Caused by: java.util.concurrent.ExecutionException: Operation failed at org.jboss.threads.AsyncFutureTask.operationFailed(AsyncFutureTask.java:74) at org.jboss.threads.AsyncFutureTask.get(AsyncFutureTask.java:268) at org.jboss.as.controller.client.impl.AbstractDelegatingAsyncFuture.get(AbstractDelegatingAsyncFuture.java:100) at org.jboss.as.controller.client.impl.AbstractModelControllerClient.executeForResult(AbstractModelControllerClient.java:127) ... 7 more Caused by: java.io.EOFException at java.io.DataInputStream.readByte(DataInputStream.java:267) at org.jboss.as.protocol.mgmt.ProtocolUtils.expectHeader(ProtocolUtils.java:83) at org.jboss.as.controller.client.impl.AbstractModelControllerClient$1.handleRequest(AbstractModelControllerClient.java:167) at org.jboss.as.protocol.mgmt.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:270) at org.jboss.as.protocol.mgmt.AbstractMessageHandler.handleRequest(AbstractMessageHandler.java:235) at org.jboss.as.protocol.mgmt.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:113) at org.jboss.as.protocol.mgmt.ManagementChannelReceiver$1.handleMessage(ManagementChannelReceiver.java:56) at org.jboss.as.protocol.mgmt.ManagementChannelReceiver.handleMessage(ManagementChannelReceiver.java:84) at org.jboss.remoting3.remote.RemoteConnectionChannel$5.run(RemoteConnectionChannel.java:452) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) {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.).
