I have some services located through a resource locator class like this:

@Path("/platform")
public interface PlatformServiceLocator {

@Path("/users/

{user}")
public UserRestService getUserService(
@HeaderParam("entity")
String entity,
@HeaderParam("ticket")
String ticket,
@PathParam("user")
String userId
);
}

@Path("/users")
public interface UserRestService extends BaseUserService { .............. }

public interface BaseUserService extends BaseCrudService<OhaUserModel>{


@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("data/ada/{user}

")
public OhaUserModel getUserDataByAdaId(
@PathParam("user")
String adaId);
}

Invoking the URL /platform/users/89080/users/data/ada/jsanchez110 was working with version 2.2.3 but not with 2.3.1. I get this error:
