      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.

       

        @Resource(name = "dataSource")
  private DataSource dataSource;
