-------------------------------

The @Inject annotation needs to remain.
This is what I meant

> As of now the deployment model of the Native Services REST API service is 
> standalone. There are several cross-cutting solutions that can be inherited 
> for free (kerberos, HA, ACLs, trusted proxy support, etc.) by the REST API 
> service if it is embedded into the RM process. In fact we can expose the REST 
> API via the same port as RM UI (8088 default). The URI path 
> /services/v1/applications will distinguish the REST API calls from other RM 
> APIs.
