Hi,
* You may want to align your email text before posting it.
* As replied to one of your earlier emails, jdk.nashorn.internal.* are
internal classes. These could be removed/changed without notice. Your
interface to nashorn is just javax.script and
jdk.nashorn.api.scripting packages. If you *really* want to play with
internals, you are essentially on your own. We try to document as much
as needed for nashorn developers. But, if you depend on internals in
*your* code, nashorn team may not be able to support the same.
