That's the problem you're having then, the fact that ntpath isn't being 
used. I'm not sure why it wouldn't work on your environment. Are you 
sure that's trunk?

What version of Windows are you using? What is the value of 
java.lang.System.getProperty('os.name')

Here's what I get:

C:\Documents and Settings\Administrator\Desktop\jython-
trunk>.\jython.bat
Jython 2.3a0+ (trunk, Jun 8 2008, 14:43:44)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_05

>>> import os
>>> os.path
<module 'ntpath' from 'C:\Documents and 
Settings\Administrator\Desktop\jython-tr

>>> os.path.isabs('/a')
True
