I'm new to jython.
I was trying to checkout source code according to http://wiki.python.org/jython/JythonDeveloperGuide, but I'm getting the following error:
$ hg clone http://hg.python.org/jython
destination directory: jython
requesting all changes

added 6355 changesets with 21144 changes to 3712 files (+12 heads)
updating to branch default
pulling subrepo CPythonLib
abort: repository [svn] https://svn.python.org/projects/python/branches/release27-maint/Lib/ not found!

And I have nothing except CPythonLib. Any idea how to work around this issue?

Jython dev FAQ does not have anything about this problem: http://wiki.python.org/jython/DeveloperFAQ

Also, the link to mailing list archive on jython-dev info page here is not valid: https://lists.sourceforge.net/lists/listinfo/jython-dev it leads to: http://code.activestate.com/aspnredir/list-gone/?list=Jython-dev which tells that the archive does not exist.
