Cannot load OpenIE model when using the open source version of CoreNLP

I downloaded the source code of coreNLP from this page and the model recommended in the README file. I create a new project in eclipse and tried to run openie by it return the following exception:

Exception in thread "main" edu.stanford.nlp.io.RuntimeIOException: Could not load clause splitter model at edu/stanford/nlp/models/naturalli/clauseSearcherModel.ser.gz

I have done the following steps:

  1. clone the repo from GitHub: https://github.com/stanfordnlp/CoreNLP.git

  2. download the latest model jar at: http://nlp.stanford.edu/software/stanford-corenlp-models-current.jar

  3. cd CoreNLP ; ant

  4. at this point you should have built the latest version of the code on GitHub

  5. set CLASSPATH to include CoreNLP/classes, CoreNLP/lib and the latest models jar

  6. run this command: java -Xmx4g edu.stanford.naturalli.OpenIE

It works fine, so I don't think there are any problems with what we are currently distributing.
