RFR: 8224184: jshell got IOException at exiting with AIX

[Toshio 5 Nakamura]

Hi,

Could you review JDK-8224184: jshell got IOException at exiting with AIX?
Also, I'd like to have a sponsor of the patch (I'm an author).

Issue: https://bugs.openjdk.java.net/browse/JDK-8224184
Webrev: http://cr.openjdk.java.net/~tnakamura/8224184/webrev.00

AIX doesn't show "min" or "time" by "stty -a" when "icanon" is defined.
This caused invalid value was trying to be set, and IOException was thrown.

Thanks,
Toshio Nakamura
