Brian Stansberry created WFCORE-4140: ---------------------------------------- Summary: Incorrect resource passed into ExtensionRegistry.remove by ExtensionAddHandler rollback handling Key: WFCORE-4140 URL: https://issues.jboss.org/browse/WFCORE-4140 Project: WildFly Core Issue Type: Bug Components: Management Reporter: Brian Stansberry Assignee: Brian Stansberry ExtensionAddHandler rollback handling passes the extension resource to ExtensionRegistry.remove when the API wants the root resource. This results in this failure: {code} 2018-09-27 17:21:19,300 ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 1) WFLYCTL0190: Step handler org.jboss.as.controller.extension.ExtensionAddHandler@4bdb1e35 for operation add at address [("extension" => "org.jboss.as.test.extension")] failed handling operation rollback -- java.lang.NullPointerException: java.lang.NullPointerException at org.jboss.as.controller.extension.ExtensionRegistry.hasSubsystemsRegistered(ExtensionRegistry.java:372) at org.jboss.as.controller.extension.ExtensionRegistry.removeExtension(ExtensionRegistry.java:342) at org.jboss.as.controller.extension.ExtensionAddHandler$1.handleRollback(ExtensionAddHandler.java:97) at org.jboss.as.controller.AbstractOperationContext$RollbackDelegatingResultHandler.handleResult(AbstractOperationContext.java:1561) at org.jboss.as.controller.AbstractOperationContext$Step.invokeResultHandler(AbstractOperationContext.java:1533) at org.jboss.as.controller.AbstractOperationContext$Step.handleResult(AbstractOperationContext.java:1515) at org.jboss.as.controller.AbstractOperationContext$Step.finalizeInternal(AbstractOperationContext.java:1472) at org.jboss.as.controller.AbstractOperationContext$Step.finalizeStep(AbstractOperationContext.java:1455) at org.jboss.as.controller.AbstractOperationContext$Step.access$400(AbstractOperationContext.java:1319) at org.jboss.as.controller.AbstractOperationContext.executeResultHandlerPhase(AbstractOperationContext.java:876) at org.jboss.as.controller.AbstractOperationContext.processStages(AbstractOperationContext.java:756) at org.jboss.as.controller.AbstractOperationContext.executeOperation(AbstractOperationContext.java:467) at org.jboss.as.controller.OperationContextImpl.executeOperation(OperationContextImpl.java:1411) at org.jboss.as.controller.ModelControllerImpl.internalExecute(ModelControllerImpl.java:423) {code} Also, ExtensionResource should not return null from getChildren. Fixing that would eliminate the NPE but the rollback handling wouldn't work properly with the wrong object being passed in. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
