Hi Tomaz,
even though a single value is not a valid json object (in your case a number), Jackson is capable of (un)marshaling this value. The better approach would be to wrap this value into a POJO.
Do you enable FEATURE_POJO_MAPPING on the client-side to make sure Jackson is (un)marshaling the entity?
final ClientConfig cc = new DefaultClientConfig();
cc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
final Client client = Client.create(cc);
