NPE when non-existent attribute name is used for list-add operation ------------------------------------------------------------------- Key: WFCORE-1997 URL: https://issues.jboss.org/browse/WFCORE-1997 Project: WildFly Core Issue Type: Bug Components: Domain Management Affects Versions: 3.0.0.Alpha12 Reporter: Chao Wang Assignee: Chao Wang When I use non-existent attribute name for 'list-add' operation, I get following NPE in server.log: {code} 12:44:24,150 ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 10) WFLYCTL0013: Operation ("list-add") failed - address: ([ ("subsystem" => "undertow"), ("server" => "default-server"), ("https-listener" => "https") ]): java.lang.NullPointerException at org.jboss.as.controller.operations.global.AbstractCollectionHandler.execute(AbstractCollectionHandler.java:92) at org.jboss.as.controller.operations.global.ListOperations$ListAddHandler.execute(ListOperations.java:108) at org.jboss.as.controller.AbstractOperationContext.executeStep(AbstractOperationContext.java:921) at org.jboss.as.controller.AbstractOperationContext.processStages(AbstractOperationContext.java:664) at org.jboss.as.controller.AbstractOperationContext.executeOperation(AbstractOperationContext.java:383) at org.jboss.as.controller.OperationContextImpl.executeOperation(OperationContextImpl.java:1364) at org.jboss.as.controller.ModelControllerImpl.internalExecute(ModelControllerImpl.java:416) at org.jboss.as.controller.ModelControllerImpl.lambda$execute$1(ModelControllerImpl.java:237) at org.wildfly.security.auth.client.PeerIdentity.runAsAll(PeerIdentity.java:431) at org.wildfly.security.auth.server.SecurityIdentity.runAs(SecurityIdentity.java:206) at org.jboss.as.controller.ModelControllerImpl.execute(ModelControllerImpl.java:237) at org.jboss.as.controller.remote.ModelControllerClientOperationHandler$ExecuteRequestHandler.doExecute(ModelControllerClientOperationHandler.java:217) at org.jboss.as.controller.remote.ModelControllerClientOperationHandler$ExecuteRequestHandler.access$400(ModelControllerClientOperationHandler.java:137) at org.jboss.as.controller.remote.ModelControllerClientOperationHandler$ExecuteRequestHandler$1$1.run(ModelControllerClientOperationHandler.java:161) at org.jboss.as.controller.remote.ModelControllerClientOperationHandler$ExecuteRequestHandler$1$1.run(ModelControllerClientOperationHandler.java:157) at org.wildfly.security.auth.client.PeerIdentity.runAsAll(PeerIdentity.java:464) at org.wildfly.security.auth.server.SecurityIdentity.runAs(SecurityIdentity.java:225) at org.jboss.as.controller.AccessAuditContext.doAs(AccessAuditContext.java:185) at org.jboss.as.controller.remote.ModelControllerClientOperationHandler$ExecuteRequestHandler$1.execute(ModelControllerClientOperationHandler.java:157) at org.jboss.as.protocol.mgmt.ManagementRequestContextImpl$1.doExecute(ManagementRequestContextImpl.java:70) at org.jboss.as.protocol.mgmt.ManagementRequestContextImpl$AsyncTaskRunner.run(ManagementRequestContextImpl.java:160) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) at org.jboss.threads.JBossThread.run(JBossThread.java:320) {code} Yeah - I understand that it is my fault that I provided bad command. But still, server should not respond with NPE. Ideally it should told me that provided list attribute does not exist for particular element and should finish operation with error.
