stanford corenlp: Unrecoverable error while loading a tagger model

Question

I need to use the StanfordTruecaser using the Java API. I have this code:

  String text = "i love paris. i am with barack obama";

  //define the properties of the pipeline to be run and add annotators to it
  Properties props = new Properties();
  props.put("annotators", "tokenize, ssplit, pos, lemma, ner, truecase");
  pipeline = new StanfordCoreNLP(props);

  //run annotators on document text
  Annotation document = new Annotation(text);
  pipeline.annotate(document);

But the POS tagger doesn't work well:

Adding annotator pos

I use Eclipse and I have linked the stanford-corenlp-3.4.jar like this:

I just add the stanford-corenlp-3.4-models.jar to the classpath in Eclipse and it works.
