FULL PRODUCT VERSION :
java version "9"
Java(TM) SE Runtime Environment (build 9+181)

ADDITIONAL OS VERSION INFORMATION :

Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
JAXB Tests with JShell.

Start JShell: jshell JAVASE --add-modules java.se.ee



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

Scanner input = new Scanner(System.in);
while (input.hasNext()) {
 ...
}

enter Ctrl-z
is not recognized / does not end the while loop


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Ctrl z should end the while loop, that is
input.hasNext() should return false
ACTUAL -
It waits for input

Ctrl-d for example gives a NoSuchElementException

Maybe JShell swallows Ctrl z

jshell> TestCaseCtrl_z.runScanner()
Enter number, first name and last name.
Enter end-of-file indicator to end input.
? 100 Bernd Meier
>>> Nr: 100
>>> PreName: Bernd
>>> Name: Meier

?


REPRODUCIBILITY :
This bug can be reproduced always.
