Jclouds with OpenStack => java.util.NoSuchElementException: apiType compute not found in directory []

Java jclouds API cannot connect to OpenStack provider.

An exception is thrown with the following message: java.util.NoSuchElementException: apiType evaluates not found in the [] directory.

Other APIs (python-novaclient, ruby-fog) work very well, so the problem seems to be language specific (API).

      try {

         jcloudOpenStack.close();
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      finally {
         jcloudOpenStack.close();
      }
   }

   private void init() {
      Iterable modules = ImmutableSet. of(new SLF4JLoggingModule());

      String provider = "openstack-nova";
      String identity = "...";   // login name
      String password = "...";   // password

      ComputeServiceContext context = ContextBuilder.newBuilder(provider)
            .endpoint("https://UltiCloud.com:5000/v2.0/")
            .credentials(identity, password)
            .modules(modules)
            .buildView(ComputeServiceContext.class);
      compute = context.getComputeService();
      nova = context.unwrap();
   }

   private void listServers() {
      Set<? extends ComputeMetadata> nodes = compute.listNodes();
      System.out.println(nodes.size());
   }

   public void close() {
      closeQuietly(compute.getContext());
   }
}

Any help or hint is appreciated.
