PredictSingle Error for binary classifier

[amod99]

I am getting below error when trying to predict for single example on binary classifier model.
java.lang.IllegalStateException: Can't invoke predictSingle() because this model outputs multiple values: 0
Below is code :

Predictor predictor = new Predictor(
new java.io.FileInputStream("path-to-model-file"));

// Create feature vector from sparse representation by map
FVec fVecSparse = FVec.Transformer.fromMap(
new java.util.HashMap<Integer, Double>() {{
put(49722683, 0.);
put(123455, 1.);
put(50000001, 1.3979400086720377);

                }});        

double pred = predictor.predictSingle(fVecSparse);

Please see this thread dmlc/xgboost#5695 . Can you add support for latest xgboost model format ?
