If you run (attached) on Windows, it gives the following result
under Jy2.2 and Py2.5:
['', 'test string', '']

but a different result under Jy2.5a:
['\r', 'test string\r', ''] was created using IDLE on Windows, and each line has standard
Windows line endings.

This change of behavior also occurs in the C implementation of Python
from version 2.2 to version 2.3+ due to universal newlines (see

Workaround: either put explicit line endings in the string ("\r\ntest
string\r\n" or read the file in (default line reading does not use
universal newlines).

Perhaps I didn't make myself clear. The behaviour of CPython2.5 is
different than Jython2.5a here.

I thought this made it a bug (?)

Noel, you are right -- this was an actual problem with Jython's parser not 
parsing in universal newlines mode (similar to #1082). I've verified your 
test case has been fixed in r5019-5020. thanks

Thanks pjenvey.  That explains why it worked for me :)
