Unwanted system properties in a connectiondefinition/adminobject from another connectiondefinition/adminobject in the same resource adapter ------------------------------------------------------------------------------------------------------------------------------------------- Key: JBJCA-902 URL: https://issues.jboss.org/browse/JBJCA-902 Project: IronJacamar Issue Type: Bug Components: Common Affects Versions: 1.1.0.Beta2, 1.0.12.Final Reporter: Simone Gotti Assignee: Stefano Maestri With the effects of issue AS7-5644 I noticed that the connection definition with missing system properties, instead of failing, was using properties from another connection definition (with a lot of consequent problems) After a lot of analysis the problem is that the org.jboss.jca.common.api.metadata.ra.Connector's system properties are polluted with the merged values of the user specified connectiondefinitions/adminobjects and these system properties's defaults are inserted in the user defined connectiondefinition/adminobject that don't define them. I think that the wrong operation is in the start method of org.jboss.as.connector.services.resourceadapters.deployment.ResourceAdapterXmlDeploymentService.java: cmd = (new Merger()).mergeConnectorWithCommonIronJacamar(raxml, cmd); I think that merging should be between IronJacamar -> Connector and not raxml -> Connector: cmd = (new Merger()).mergeConnectorWithCommonIronJacamar(ijmd, cmd); After this change I see that the Connector is clean and no unwanted default are added inside my connectiondefinitions/adminobjects I'll attach the possible pull request.
