NPE on jaxrs subsystem of FAILED deployment -------------------------------------------- Key: WFLY-9450 URL: https://issues.redhat.com/browse/WFLY-9450 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 15.0.1.Final Reporter: Claudio Miranda Assignee: Bartosz Baranowski Priority: Major Fix For: 19.0.0.Beta1 read deployment resources of a server, where one deployment is in failed status, throws a NPE and doesn't return the list of deployed applications. To reproduce, get the kitchensink from quickstarts, change the persistence.xml to point to ExampleDS datasource, deploy and assign to main-server-group. Then disable ExampleDS, restart server-one. Run the following command: {code} /host=master/server=server-one:read-children-resources(child-type=deployment,include-runtime,recursive) {code} {code} deploy ~/redhat/git/quickstart/kitchensink/target/kitchensink.war --server-groups=main-server-group /profile=default/subsystem=datasources/data-source=ExampleDS:write-attribute(name=enabled,value=false) /profile=full/subsystem=datasources/data-source=ExampleDS:write-attribute(name=enabled,value=false) /profile=full-ha/subsystem=datasources/data-source=ExampleDS:write-attribute(name=enabled,value=false) /host=master/server=server-one:reload /host=master/server=server-one:read-children-resources(child-type=deployment,include-runtime,recursive) {code} The exception in server.log {code} 2017-10-17 17:08:02,778 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 32) WFLYCTL0013: Operation ("read-attribute") failed - address: ([ ("deployment" => "kitchensink.war"), ("subsystem" => "jaxrs"), ("rest-resource" => "org.jboss.as.quickstarts.kitchensink.rest.MemberResourceRESTService") ]): java.lang.NullPointerException at org.wildfly.extension.undertow.deployment.UndertowDeploymentService.getDeployment(UndertowDeploymentService.java:170) at org.jboss.as.jaxrs.DeploymentRestResourcesDefintion$AbstractRestResReadHandler.execute(DeploymentRestResourcesDefintion.java:183) at org.jboss.as.controller.operations.global.ReadAttributeHandler.doExecuteInternal(ReadAttributeHandler.java:172) at org.jboss.as.controller.operations.global.ReadAttributeHandler.doExecute(ReadAttributeHandler.java:135) at org.jboss.as.controller.operations.global.GlobalOperationHandlers$AbstractMultiTargetHandler.execute(GlobalOperationHandlers.java:231) {code} The CLI results doesn't display the error message {code} [domain@localhost:9990 /] /host=master/server=server-one:read-children-resources(child-type=deployment,include-runtime,recursive) { "outcome" => "success", "result" => undefined, "failure-description" => undefined } {code} There is a similar problem while reading a specific deployment, {code} /host=master/server=server-one/deployment=kitchensink.war:read-children-resources(child-type=subsystem,recursive) {code} results in the following error in server.log {code} 2017-10-17 17:16:09,857 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 32) WFLYCTL0013: Operation ("read-attribute") failed - address: ([ ("deployment" => "kitchensink.war"), ("subsystem" => "ejb3"), ("stateless-session-bean" => "MemberRegistration") ]) - failure description: "WFLYEJB0370: EJB component for address [ (\"deployment\" => \"kitchensink.war\"), (\"subsystem\" => \"ejb3\"), (\"stateless-session-bean\" => \"MemberRegistration\") ] is in state DOWN, must be in state UP" {code}
