Description

I have bare windows 8 with fresh JDK. I run Groovysh in cmd.exe.
Groovysh 2.1.9 works as expected.

Groovysh 2.2.0 doesn't react to arrow keys and Del, i.e. up key doesn't show previous command, left key doesn't shift cursor etc.

After some investigation I found what is working:
ctrl-a go to beginning of line
ctrl-e go to End of line
ctrl-f go Forward one char
ctrl-b go Backward one char
ctrl-d delete the char
ctrl-h and backspace = delete left char
ctrl-p recall previous line
ctrl-n recall next line
ctrl-s search
ctrl-r reverse search
It's nice and feel myself like a Linux hacker, but I want arrow keys too

I tried different options:

• upgrade jline2.10 to 2.11 - no effect
• --terminal=unix - it helps, but duplicate prompt (groovy:000>) and no more colors in console

Looks like problem lies in new jline v2 (groovysh 2.1.9 uses jline1.0)
