Type: Bug
Component: tools
Sub-Component: jshell
Affected Version: 12

Submitted: 2018-12-20
Updated: 2018-12-29
Resolved: 2018-12-29

ADDITIONAL SYSTEM INFORMATION :
openjdk full version "12-ea+24"

A DESCRIPTION OF THE PROBLEM :
Using Ctrl+D shortcut to exit JShell prints a stacktrace, instead of just exiting JShell as it used to do. This regression is most likely caused by JDK-8214491, which was resolved in b24

REGRESSION : Last worked in version 11.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
open JShell and press Ctrl+D

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JShell exits without printing anything
ACTUAL -
JShell prints the following stacktrace and then exits:
Exception in thread "main" jdk.internal.org.jline.reader.EndOfFileException
