NPE when trying to recursively remove the EJB subsystem ------------------------------------------------------- Key: WFLY-9405 URL: https://issues.jboss.org/browse/WFLY-9405 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 11.0.0.CR1 Reporter: Brian Stansberry Assignee: Brian Stansberry This fails: {code} [standalone@localhost:9990 /] /subsystem=ejb3:remove { "outcome" => "failed", "failure-description" => "WFLYCTL0158: Operation handler failed: java.lang.NullPointerException", "rolled-back" => true } {code} with this in the server log: {code} 15:53:42,572 ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 4) WFLYCTL0013: Operation ("remove") failed - address: ([ ("subsystem" => "ejb3"), ("service" => "remote"), ("channel-creation-options" => "MAX_OUTBOUND_MESSAGES") ]): java.lang.NullPointerException at org.jboss.as.controller.OperationContextImpl.readResourceFromRoot(OperationContextImpl.java:894) at org.jboss.as.controller.OperationContextImpl.readResourceFromRoot(OperationContextImpl.java:884) at org.jboss.as.controller.RestartParentResourceHandlerBase.getModel(RestartParentResourceHandlerBase.java:216) at org.jboss.as.controller.RestartParentResourceHandlerBase.access$000(RestartParentResourceHandlerBase.java:39) at org.jboss.as.controller.RestartParentResourceHandlerBase$1.execute(RestartParentResourceHandlerBase.java:66) at org.jboss.as.controller.AbstractOperationContext.executeStep(AbstractOperationContext.java:980) at org.jboss.as.controller.AbstractOperationContext.processStages(AbstractOperationContext.java:726) at org.jboss.as.controller.AbstractOperationContext.executeOperation(AbstractOperationContext.java:450) at org.jboss.as.controller.OperationContextImpl.executeOperation(OperationContextImpl.java:1402) at org.jboss.as.controller.ModelControllerImpl.internalExecute(ModelControllerImpl.java:418) ... {code} I believe a post-boot add of this resource would fail as well. Problem is ChannelCreationOptionRemove and ChannelCreationOptionAdd in RemoteConnectorChannelCreationOptionResource use an incorrect parentKeyName. These handlers extend RestartParentResourceHandlerBase but are passing the *value* of the parent element as "parentKeyName" instead of its *key*; i.e. "remote" instead of "service". Even though this code has been like this since 2012, this is somewhat a regression since before the current version our standard configs did not include resources of this type. So users could hit this in previous releases but now they are more likely to.
