warning: io/console not supported; tty will not be manipulated #354
Description
I know that http://jira.codehaus.org/browse/JRUBY-1608 is marked for 1.7.1 to be resolved.
Just want to say that after upgrading from 1.7.0.RC2 to 1.7.0 I started to see this warning (in rake test and rails server):
io/console not supported; tty will not be manipulated
Nothing breaks in the app, just the warning.

speed 38400 baud; line = 0;
