> Within WildFly Swarm we need the ability to override the `javax.ws.rs.client.ClientBuilder` service file for a deployment to provide custom handling for implementing Eclipse MicroProfile.
> With a service file present in the deployment, the existing RESTEasy service file is always found first because the deployment module is added as a dependency after other non local dependencies. See https://github.com/wildfly/wildfly-core/blob/master/server/src/main/java/org/jboss/as/server/deployment/module/ModuleSpecProcessor.java#L241-L250
> After discussing with [~dmlloyd] on IRC, he agreed this was a bug and a better solution was for the deployment's dependency to always be first if `isLocalLast()` is false, and instead remove any spec packages that might be present on the deployment path instead.
> He explained the purpose of this ordering was to prevent a user deploying `javax.servlet.api` and breaking things, but it appears this can be achieved by alternative methods.
