jaxrs-spec: @Path-Generation is wrong for resource-path "/"

Created by: attrobit

Description

When we define our primary resource under path "/" (see declaration file), jaxrs-spec generates the following stub:

@Path("/default")
@Api(description = "the default API")
...
public interface DefaultApi {
...
}

The generated path "/default" is wrong and the name of the interface is confusing. Additionally to that the following interface will be generated for the path "/{uuid}":

@Path("/{uuid}")
@Api(description = "the {uuid} API")
...
public interface UuidApi {
}

Steps to reproduce

Define some primary resources under path "/" (see example contract) and generate the jaxrs stubs.

My suggestion is using the tags to grouping the methods into interfaces like jaxrs-cxf.
