------------------------------------------------------------------
The {{gets}} of jruby 9.x can't handle the {{Control-M}} which is used as the
character of {{ENTER}}. It causes trouble if hbase shell prompts the user for
choices(y/n). There is a related
[issue|https://github.com/jruby/jruby/issues/1372] in jruby but it hasn't be
resolved yet. We should remind user to use {{Ctrl-J}} instead. [~mdrob]
[~busbey] WDYT?

> Ruby 1.8.7 is no longer maintained.
> The TTY library in the old jruby is bad. The newer one is less bad.
> Since this is only a dependency on the hbase-shell module and not on
> hbase-client or hbase-server this should be a pretty simple thing that
> doesn't have any backwards compat issues.
