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.

how can i solve those two errors.i have wrap this object using
ScripObjecMirror.but than ain't help
thank you
