Sorry to keep pecking at your poor shell, but fansh does not handle SIGSUSP (ctrl-z) at all. I only bring it up because the other big REPLs I use (python, irb, erl, gsi) all handle it nicely:

I don't think we can trap signals in Java without resorting to sun APIs.
What happens if you just suppress IOExceptions on readLine?
f00biebletch: irb handles it well, jirb however behaves exactly like fansh
f00biebletch what platform are you on?
I believe this can be made to work with jline which is what I used for fansh to support completion and cmd line editing.
I'm OSX, would expect same behavior on linux etc. It is certainly a java issue, not sure how important it is, especially if I break the ctrl-d habit.
I think you're right about jline, but, again, doubt it's worth the trouble.
