Julian Hyde commented on PHOENIX-3299:
--------------------------------------
If you hard-code a package name or class name, shade can't re-locate it. But it
you instantiate an object, then ask it its class name or package name, it will
return the shaded path. Can you do that? Maybe have a dummy singleton object,
say {{enum Dummy { INSTANCE } }}.
> Janino could not work in shaded package
