a)  for i in range(100000):
        from org.python import Version

b)  for i in range(100000):
        import org.python.Verion as Version

a) is massively slower than b).

Looks like the problem is the below from imp.java which makes it attempt to load the nonexistent org.python.__path__ because __path__ is never set on the java package object.

    private static void ensureFromList(PyObject mod, PyObject fromlist, String name,
                                       boolean recursive) {
            if (mod.__findattr__("__path__") == null) {
                return;
            }
