The return value from PythonInterpreter.get() is always a PyObject
instance. You need to explicit convert the returned PyObject instance to
an instance of your java class like this:

Object tmp = interp.get("cl").__tojava__(ListBO.class);
if (tmp != Py.NoConversion) {
   ListBO newobj = (ListBO) tmp;
}

If the "cl" variable can't be converted to a ListBO, the constant value
of Py.NoConversion is returned.
