When trying to launch the Ensemble sample application, I got a crash resulting from the line 165 of SampleHelper.java:

    BufferedReader reader = new BufferedReader(new InputStreamReader(SampleHelper.class.getResourceAsStream("samplesAll.txt")));

There is no "samplesAll.txt" file anywhere in the project, so this raises NullPointerException and crashes the app.

Full stack trace:
