Trying 2.7b1, I get:

gsnedders@vanveen:~$ ~/local/jython2.7b1/jython

  File "/home/gsnedders/local/jython2.7b1/Lib/locale.py", line 358, in normalize
    fullname = localename.translate(_ascii_lower_map)
TypeError: translate() only works for 8-bit character strings

Oddly, a quickly minimized version of it works fine:

>>> _ascii_lower_map = ''.join(
...     chr(x + 32 if x >= ord('A') and x <= ord('Z') else x)
...     for x in range(256)
... )
>>> "a".translate(_ascii_lower_map)
'a'

localename and _ascii_lower_map are both of type str, so the error message seems bogus.

Playing about further I found I had a non-ASCII character in LANGUAGE in my environment (how on earth did *that* get there!?), so the following fails, giving the above exception:

gsnedders@vanveen:~$ export LANGUAGE="$(echo -n -e '\xffen_GB')"
gsnedders@vanveen:~$ ~/local/jython2.7b1/jython -m optparse

An odd setup, but probably something that shouldn't break just because of a non-ASCII character. Probably some underlying bug around translate, however.

It's an unlikely scenario as gsnedders mentions, but we should fix. I think this is one of the cases where the underlying Java environment is providing us unicode - see what appears to be a somewhat related bug #1841
