possible Scanner input bug in jshell?

Thanks for reporting this.  It is a known issue that System.in does not 
work:

      https://bugs.openjdk.java.net/browse/JDK-8131023?filter=25683

It is possible that the current work inter-process communication issues 
(see the other issue you sent) may provide an avenue for addressing 
this.  In the end, I have re-assigned and raised the priority.

Thanks,
Robert

The output works fine, but jshell appears to hang up when doing a Scanner nextLine() method - CTRL-C and CTRL-Z don't interrupt this, so at this point I have to close the cmd window manually.
