Установка Setuptools в Jython

Последний автономный Jython (2.7 final), последние инструменты настройки:

C:\projects_intellij\test_jython>jython.bat ez_setup.py

C:\projects_intellij\test_jython>java -jar "C:\projects_intellij\test_jython\jython-standalone-2.7.0.jar" ez_setup.py

  File "C:\projects_intellij\test_jython\jython-standalone-2.7.0.jar\Lib\subprocess.py", line 1311, in _execute_child
TypeError: args must contain only strings

Есть ли способ установить это с помощью Jython? Должен ли я использовать Jython, установленный установщиком, а не автономный?

Платформа: Win 7 x64.
