Union predicate appears to have indexes range issue in evaluate

The implementation of evaluate() in UnionPredicate (included below for reference) appears to have an issue when iterating over the indexes array. The counting loop goes from 0 to indexes.length. I believe it should go from 0 to current.

    public List<Value> evaluate(List<Value> values, List<Value> results) {
        for(Value value: values) {
            int currentValueSize = value.size();
            for(int j=0;j<Array.getLength(indexes);j++) {
                if(indexes[j] >= 0 && indexes[j] < currentValueSize) {
                    results.add(value.get(indexes[j]));
                } else if(indexes[j] < 0 && (currentValueSize - indexes[j]) >= 0) {
                    results.add(value.get(currentValueSize + indexes[j]));
                }
            }
        }
        return results;
    }
