Unable to remove the default datasource binding from the ee subsystem --------------------------------------------------------------------- Key: WFLY-14025 URL: https://issues.redhat.com/browse/WFLY-14025 Project: WildFly Issue Type: Bug Components: EE, JCA Reporter: Lin Gao Assignee: Tomasz Adamski Priority: Major Labels: Regression, downstream_dependency Attachments: reproducer-spring.war, reproducer-spring2.war, reproducer2.war, standalone.xml EAP 7.2+ is creating a dependency on the DefaultDataSource when it should not. If the default datasource is removed from the ee subsystem and an application is deployed with a class that has @Resource specifying a name to inject which is not linked to the default datasource, it should NOT fail with a missing dependency. This was found with a Spring application, where Spring configuration is defining java:comp/env/dataSource to link to the real datasource.  In EAP 7.1 the application deployed with no issue, in EAP 7.2+ JBoss is failing the deployment due to the datasource=... being removed from the default bindings in the ee subsystem.   {code:java}   @Resource(name = "dataSource")   private DataSource dataSource; {code}   {code:java} 18:08:15,547 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "reproducer2.war")]) - failure description: {     "WFLYCTL0412: Required services that are not installed:" => ["jboss.naming.context.java.module.reproducer2.reproducer2.DefaultDataSource"],     "WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.reproducer2.reproducer2.env.non-existant is missing [jboss.naming.context.java.module.reproducer2.reproducer2.DefaultDataSource]"] }{code}
