Using NLTK3.0 with Jython

Hi,

I want to use NLTK 3.0 with Jython.

I have tried Jython2.5.3 and Jython2.7beta3 versions with Pyhton 2.7.3
version.

when running 'import nltk' in the in the Jython shells i get the following
errors

1. Jython2.5.3 with Pyhton 2.7.3 & NLTK 3.0

>>> import sys
>>> sys.path.append('/usr/local/lib/python2.7/dist-packages/')
>>> import nltk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/nltk/__init__.py", line 35
    except IOError as ex:
                  ^
SyntaxError: mismatched input 'as' expecting COLON



2. jython2.7b3 with Pyhton 2.7.3 & NLTK 3.0


>>> import sys
>>> sys.path.append('/usr/local/lib/python2.7/dist-packages/')
>>> import nltk
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/nltk/__init__.py", line 104,
in <module>
    from nltk.decorators import decorator, memoize
  File "/usr/local/lib/python2.7/dist-packages/nltk/decorators.py", line
183, in <module>
    @decorator
  File "/usr/local/lib/python2.7/dist-packages/nltk/decorators.py", line
172, in decorator
    return update_wrapper(_decorator, caller)
  File "/usr/local/lib/python2.7/dist-packages/nltk/decorators.py", line
83, in update_wrapper
    infodict = infodict or getinfo(model)
  File "/usr/local/lib/python2.7/dist-packages/nltk/decorators.py", line
76, in getinfo
    return dict(name=func.__name__, argnames=argnames, signature=signature,
AttributeError: 'function' object has no attribute '__defaults__'

I have also gone through the mail thread
http://sourceforge.net/p/jython/mailman/message/32929832/, where the final
conclusion i understood is to wait for beta4 release of  jython2.7.

My question is can I get any patch to work with jython2.7b3 with Pyhton
2.7.3 & NLTK 3.0? If so kindly help me in adding the patch.

Or is there a way to rectify the mismatched input 'as' expecting COLON  error
in Jython2.5.3 with Pyhton 2.7.3 & NLTK 3.0?

Kindly help.

Thanks in advance.
