Description

Possibly fixed by now, but if I do this:

$ jruby -S irb
>> a = 3
=> 3
<now hit ctrl+z>

  1. hack in bash
    $ fg # in bash

then type in anything, it no longer appears in the console. Hitting enter shows that it is entered, just not echoed to the screen for some reason.
Cheers!

This has been a problem with jline over the years; suspending a terminal and restarting it does not restart the readline session properly.

We should probably look at moving to jline2, which has many more updates.

I updated JRuby master to jline2, and it doesn't seem to have this problem. There's some odd echoing artifacts on resume of the process, but otherwise it works fine.

    Add readline, remove some unnecessary excludes from spec runs.
