[ShinyaYoshida]

Hi Kishori and Robert,

I've filed this as a P4 bug with a description and a comment by quoting
your emails:
Please fix the ticket if there is some problems...(of course, after when
you be back)

https://bugs.openjdk.java.net/browse/JDK-8175304

Thank you for using jshell and reporting the problem!

Regards,
