WildFly discovery subsystem registers capabilities using an ambiguous contract ------------------------------------------------------------------------------ Key: WFCORE-4535 URL: https://issues.jboss.org/browse/WFCORE-4535 Project: WildFly Core Issue Type: Bug Components: Discovery Affects Versions: 9.0.1.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Critical The discovery subsystem registers capabilities of the form RuntimeCapability<Void> with a service type of DiscoveryProvider.class with the model. However, during runtime it registers capabilities of the form RuntimeCapability<DiscoveryProvider> with the OperationContext using the same name. This violates the capability contract. Since the capability specified during resource registration is what defines the contract, and since non-trivial discovery provider implementations cannot reasonably register an implementation during the model phase without requiring runtime dependencies, we should prefer the former definition over the latter.
