I guess that's also the reason why 'import collections' does not work, then?

Here's the code I use to integrate the Jython class into Java:

    private MetaModel prepareMetaModel() throws IOException {
        PySystemState engineSys = new PySystemState();
        Py.setSystemState(engineSys);
        PythonInterpreter interpreter = new PythonInterpreter();
        InputStream resourceAsStream = Plugin.getResource("/src-py/MetaModel.py");
        interpreter.execfile(resourceAsStream);

        interpreter.exec("x = MetaModelImpl()");
        Object x = interpreter.get("x").__tojava__(MetaModel.class);
        MetaModel metaModel = (MetaModel) x;

        return metaModel;
    }

I guess the problem could be the empty PySystemState? Strangely, other packages like time seem to work just fine as it is.
