There are code paths in the connector module that result in dependencies on services provided by the legacy security subsystem being added to ds and r-a services even though the ds or r-a config doesn't require the depended on services. This will force users to retain the legacy subsystem in their config even though it is otherwise unnecessary.

The services are org.jboss.as.security.service.SubjectFactoryService and org.jboss.as.security.service.SimpleSecurityManagerService.
