problem running jshell 12 or later using AT&T's UWIN ksh as its environment on Win 10

[Yacobellis, Robert]

Hi, all,

This is probably not something you can fix for me, since I doubt that many others are using AT&T's UWIN to simulate Unix on Windows 10 ...

Through Java 11.0.3 I've been able to run jshell with no problems under ksh using UWIN; starting with Java 12 and through Java 13ea today running it throws an exception - I've attached captured outputs that indicate the PosixTerminal is unable to parse "columns".

Do you have any suggestions about how I might change the environment of jshell to get this to work? I think I remember some jline-related changes that were put into Java 12 that might be causing this interaction problem.

Thanks,

PS jshell 12 & 13ea work fine in a Windows 10 cmd console, so I can always run it there if I have to.
