The ScriptUtils methods are supposed to be called only from *scripts* - which the javadoc comments makes it very clear. Why do you call it from Java? When calling from script, the particular static type of method parameters should not make any difference.

Besides, when crossing Javascript to java boundary, all script objects are mirrored (wrapped) automatically now. There should be no need for Java side to explicitly call wrap/unwrap at all. Will you please given an example of your use-case?

Also, what other API instability concerns you have? Will you please be more explicit on those?

Thanks,

Hello everyone,

on October 7th, Richard Evans posted to this mailing list (with the same 
subject as me):

"Sometime after jdk1.8u32 this method changed to take an internal 
jdk.nashorn.internal.runtime.ScriptObject argument.  This means that code compiled 
with 1.8u20 will not work with later releases, and vice versa.

Was this change intentional?  Is this API now fixed for all future jdk1.8 and 
1.9 releases?“

I would very much like to know the same thing. Unfortunately, he didn’t get an 
answer. Could anyone please provide some insights?

We’ve been using Nashorn since early 2015 now and there has been more that one 
occasion, when a newer JDK behaved differently (in respect to Nashorn) than an 
older JDK (up to the point of the aforementioned compile error). I guess my 
real question is, how stable is Nashorn’s API?

Thanks
Timo
