In Java's Nashorn engine, when you eval code, if you do this
var e = Packages.org.bukkit["event"]
e will be null.
But, one thing that I found, is that if I do this
var anothervar = Packages.org.bukkit.event
var e = Packages.org.bukkit["event"]
e (as well as anothervar) will be the org.bukkit.event package.
Why does Nashorn have it so after I access a package with dot notation, it will start working with the bracket notation?
From what I am looking at, it is a Java 8 bug, so in the meantime, a hackish workaround can be eval-ing the package with the dot notation
e.g.
eval("Packages.org.bukkit."+"event.server"); //or whatever variable it may be
EDIT
The bug has been fixed, so it should work now.
