In a regular cygwin shell, everything works fine. However, if one starts X windows and runs an xterm (very popular for X-style cut/paste, etc.), it was possible with earlier 2.5 betas to trick jython into working by adding the option "-Djline.terminal=jline.UnixTerminal" and running "stty -icanon min 1 -echo" beforehand. A hack, but it got the job done. Now, even this hack does not work. Interactive sessions have no readline support and look like:

print "hi"
hi

instead of:

Jython 2.5.2rc2 (Release_2_5_2rc2:7167, Oct 24 2010, 22:48:30)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_20
Type "help", "copyright", "credits" or "license" for more information.
>>> print "hi"
hi
>>>

A few clues I noticed in the cygwin xterm:
1) sys._jy_interpreter is InteractiveConsole instead of JLineConsole
2) sys.stdin.isatty() is False. This should be true, and it seems to determine which console object is used.
