Intermittent failure of deployment containing two datasources in -ds.xml ------------------------------------------------------------------------ Key: WFLY-5030 URL: https://issues.jboss.org/browse/WFLY-5030 Project: WildFly Issue Type: Bug Components: JCA Affects Versions: 10.0.0.Beta1 Reporter: Jan Blizňák Assignee: Stefano Maestri Fix For: 10.0.0.Final Attachments: one-datasource.jar, two-datasources.jar Running smoke runs of JBossWS in EAP7, I occasionally hit test failure of WSRMStoreFeatureTestCase (from JBossWS testsuite). The testcase uses deployment that should add some datasources, but deploying ends up with: {code} org.jboss.msc.service.StartException in service jboss.data-source.java:jboss/datasources/rmclientdb.statistics: Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1904) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.IllegalArgumentException: WFLYCTL0218: A node is already registered at '/deployment=*/subsystem=datasources/data-source=*/statistics=jdbc' at org.jboss.as.controller.registry.NodeSubregistry.register(NodeSubregistry.java:86) at org.jboss.as.controller.registry.ConcreteResourceRegistration.registerSubModel(ConcreteResourceRegistration.java:180) at org.jboss.as.connector.services.datasources.statistics.DataSourceStatisticsService.start(DataSourceStatisticsService.java:85) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1881) ... 3 more {code} After some debugging, the problematic scenario seems to be: 1) there is a deployment (jar/war, doesn't matter) containing -ds.xml configuration file 2) this file contains definition of at least two datasources to be added
