OK so I downloaded fresh versions of both. If put in the above
workaroudn for the TCP_NODELAY issue. And upon running I get:
C:\jython2.5.1>jython.bat \web2py2\web2py.py
WARNING:root:no file locking
WARNING:root:unable to import dbhash
WARNING:root:GUI not available because Tk library is not installed
unpacking apps; this may take a few seconds...
Traceback (most recent call last):

File "C:\web2py2\gluon\widget.py", line 726, in start

raise OSError(0, "couldn't delete file", path)
OSError: [Errno 0] couldn't delete file: 'admin.tar'
So I wrapped that in a try-block. The next issue to deal with is a
lack of sqlite (Welcome app). That's not difficult but annoying.
Just delete the db.py model (for now). And that gets us to the root
issue I can't get past with any template. Here's the traceback for
the Welcome app main page:

for item in regex.finditer(text, i):
RuntimeError: maximum recursion depth exceeded
This is Jython 2.5.1 fresh install, 1.71.2 fresh install with only the
changes I've mentioned in this post. There are no bugs for this in
Jython as the answer has always been "just increase the recursion
depth". I've tried setting the recursion depth to something
ridiculously high and that made no difference.
Can anyone else confirm/deny this? I'm testing on Windows, can we get
a Linux user to test this?
