jython manage.py runserver

Question

Windows 7, 64bit
Jython 2.5.4rc1
Django 1.4.5
Django_jython-1.3.0

I am trying to follow the tutorial @ https://docs.djangoproject.com/en/1.4/intro/tutorial01/

django-admin.py startproject mysite

worked fine and I now have my project structure. But then

jython manage.py runserver

generated a gigantic traceback error. Here are just excerpts from the start, middle and end.
It begins:

Traceback (most recent call last):  
  File "manage.py", line 10, in (module)  
    execute_from_command_line(sys.argv)  
  File "E:\jython2.5.4rc1\Lib\site-packages\django\core\management\__init__.py", line 443, in execute_from_command_line  
    utility.execute()  
...

continues:

...  
  File "E:\jython2.5.4rc1\Lib\site-packages\django\utils\importlib.py", line 35, in import_module  
    __import__(name)

        at org.python.objectweb.asm.CLassReader.accept(Unknown Source)  
        at org.python.objectweb.asm.ClassReader.accept(Unknown Source)  
...

concludes:

        at org.python.util.jython.run(jython.java:247)  
        at org.python.util.jython.main(jython.java:129)  

java.lang.ArrayIndexOutOfBoundsException: java.lang.ArrayIndexOutOfBoundsException 2560

This is definitely not what is to be expected. I can imagine that it is some kind of configuration problem, but I have no idea what.

Many thanks in advance for all assistance.

I look forward to any advice.

Can you paste in the full stacktrace if possible? Don't break it up. — Josh Smeaton, Mar 16 '13 at 23:43
Not a problem (I didn't want to create an enormous post unneccesarily): — SeeGull, Mar 17 '13 at 09:22
What version of django are you using? I believe up to django 1.3 (maybe 1.4) is supported with DOJ. — Josh Smeaton, Mar 18 '13 at 01:03
The system info is at the top of the post. It is a first time installation of 'Jython 2.5.4rc1', 'Django 1.4.5' and 'Django_jython-1.3.0'. — SeeGull, Mar 18 '13 at 08:49
Can you post the full contents of your settings.py file? Also, try downgrading to django 1.3 and see if it all begins working. django-jython 1.3.0 was built for django 1.3, and while it may support django 1.4, I can't find any guarantees anywhere other than the official django site. I've worked with django on jython, and it wasn't pleasant. If you can do straight django on python, you really should. — Josh Smeaton, Mar 18 '13 at 11:14
Jython was an experiment. I have now changed to Python2.7.3 and Django 1.5. I may re-visit this matter in the future but for now I shall take the simple way out. — SeeGull, Mar 19 '13 at 13:21
