This is working fine for me -

Maven Dependencies :

        
            edu.stanford.nlp
            stanford-corenlp
            3.5.2
            models
        
        
            edu.stanford.nlp
            stanford-corenlp
            3.5.2
        
        
            edu.stanford.nlp
            stanford-parser
            3.5.2
        

Java Code :

public static void main(String[] args) throws IOException {
        String text = "This World is an amazing place";
        Properties props = new Properties();
        props.setProperty("annotators", "tokenize, ssplit, pos, lemma, parse, sentiment");
        StanfordCoreNLP pipeline = new StanfordCoreNLP(props);

        Annotation annotation = pipeline.process(text);
        List sentences = annotation.get(CoreAnnotations.SentencesAnnotation.class);
        for (CoreMap sentence : sentences) {
            String sentiment = sentence.get(SentimentCoreAnnotations.SentimentClass.class);
            System.out.println(sentiment + "\t" + sentence);
        }
    }

Results :

Very positive This World is an amazing place
