(terminal session was disconnected.)

Recreate steps:
1. Open a terminal on AIX or remote login to AIX
2. Launch jshell
3. Type "/exit"
Then, IOException was thrown. If you are using a local terminal, it was closed.
If you are using remote login, the session was closed.

Evaluation:
The default value of AIX console is below.
AIX doesn't show min/time by "stty -a", if icanon is defined.

$ stty -a

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = ^@; eol2 = ^@;
start = ^Q; stop = ^S; susp = ^Z; dsusp = ^Y; rprnt = ^R; werase = ^W;

echoctl echoke -flusho

Then stored values of 'min' and 'time' are undefined (-1).
After that, the -1 was to binary as '11111111111111111111111111111111'b.
Finally, the terminal session was disconnected.

The problem didn't occur with Java11.0.3.
I confirmed it occurred with Java 12, 12.0.1 and 13.
