### Question:
HessianConfig { public static SerializerFactory createFactory( String[] factoryNames, EntityResolver resolver) { return createFactory(factoryNames, resolver, Collections.emptyList()); }  static SerializerFactory createFactory(
            String[] factoryNames,
            EntityResolver resolver); static SerializerFactory createFactory(
            String[] factoryNames,
            EntityResolver resolver,
            Collection<String> additionalWhitelist);  }### Answer:
@Test public void testLoadFactoryNoExtensions() { SerializerFactory factory = HessianConfig.createFactory(null, null); assertNotNull(factory); }
