Estoy tratando de empaquetar Grizzly con Jersey como un tarro único usando el complemento de sombra Maven. Pero siempre recibo el mensajeNo container provider supports the type class org.glassfish.grizzly.http.server.HttpHandler

El código funciona bien en Eclipse, pero no en un contenedor empaquetado:

public class Main {

private static URI getBaseURI() {
    return UriBuilder.fromUri("http://localhost/").port(9998).build();
}

public static final URI BASE_URI = getBaseURI();

protected static HttpServer startServer() throws IOException {
    System.out.println("Starting grizzly...");
    ResourceConfig rc = new PackagesResourceConfig("share.test");
    rc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
    return GrizzlyServerFactory.createHttpServer(BASE_URI, rc);
}

public static void main(String[] args) throws IOException {
    HttpServer httpServer = startServer();
    System.in.read();
    httpServer.stop();
}    
}

Aquí está la excepción completa

$ java -jar target/webServiceTest-0.0.1-SNAPSHOT.jar

Estoy construyendo el paquete jar usando Maven con

<build>
 <plugins>
  <plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-shade-plugin</artifactId>
   <version>1.5</version>
   <configuration>
   <transformers>
   <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
     <manifestEntries>
      <Main-Class>share.test.Main</Main-Class>
      <Build-Number>1</Build-Number>
     </manifestEntries>
    </transformer>
  </transformers>
 </configuration>
<executions>
 <execution>
  <phase>package</phase>
   <goals>
    <goal>shade</goal>
   </goals>
 </execution>
</executions>
</plugin>
</plugins>
</build>

Necesito cambiar el complemento de sombra para incluir algo más?
