Unsafe.defineAnonymousClass no longer exists in Java17!

[Luc Chapon]

Hello all

First message here

We are facing a problem re Nashorn (latest) and java17

In Context.java, line 330, you try to get a handle to a no longer existent
method, Unsafe.defineAnonymousClass

And fail of course.

I’m trying to rewrite this part for our own temporary urgent need according
to this.

Removal
of sun.misc.Unsafe::defineAnonymousClass*

sun.misc.Unsafe::defineAnonymousClass API has been removed in JDK 17. The
API replacement is java.lang.invoke.MethodHandles.Lookup::defineHiddenClass
 and java.lang.invoke.MethodHandles.Lookup::defineHiddenClassWithClassData.


Are you aware of the problem? Is there a fix already available?

Thank you!
