>             Project: TOREE
>          Issue Type: Bug
>          Components: Kernel
>    Affects Versions: 0.5.0
>            Reporter: Charles Hedrick
>            Priority: Major
>
> This isn't exactly a bug, but a report.
> I'm trying to get toree to work with spark 3. I've gotten 0.5.0 rc2 working, 
> but it wasn't easy.
> First, there's no pip version so I had to hack up a jupyter kernel directory.
> I found that it would only work with Java 11. But with java 11, I needed
> "JDK_JAVA_OPTIONS": "-Dscala.usejavacp=true",
> I guess that's OK, but I think you can set that in the code.
