To get instances implementing given service:

import java.util.ServiceLoader;
private Map<String, ServiceInterface> collect() {

    ServiceLoader<ServiceInterface> loader = ServiceLoader.load(ServiceInterface.class);
    Map<String, ServiceInterface> impls = new HashMap<>();

    for (ServiceInterface impl : loader) {
        impls.put(impl.getClass().getSimpleName(), impl);
    }
    return impls;
}
