RFR: 8224184: jshell got IOException at exiting with AIX

[Toshio 5 Nakamura]

Hi,

I think lacking of testcase may be a concern of my proposal.
Honestly, I couldn't create an automated testcase of this problem.
I tried to use shell script like below, but it cannot execute the
problematic path.

$ echo "/exit" | jshell

I think the testcase needs to run on 'pty'.

Manual instructions are very simple, though.
1. Open a terminal on AIX (or telnet/ssh to AIX)
2. Launch jshell
3. Type "/exit"

Could you give me any advice?
