Urgent: Can't get REPL to work anymore (for a live demo!)

[Mani Sarkar]

Hi Roy,

Have you had a look at this ?

https://adopt-openjdk.ci.cloudbees.com/view/OpenJDK/job/langtools-1.9-linux-x86_64-kulla-dev/lastSuccessfulBuild/artifact/
 (just bookmark it, we have archives of working versions, for future events)

We build one at every change. When you run the 0.610 version you get the
below:

*$ java -jar kulla-0.610-20150623005842.jar*

|  Welcome to JShell -- Version 0.610
|  Type /help for help

->

I hope by now your issue is resolved.

Cheers,
Mani
