graal-js - passing JS native object to Java - com.oracle.truffle.object.enterprise.b

[Andreas Woess]

Hi Adam!

This is an implementation class that is leaked, probably through Java
interop. We're currently reworking the value conversions so that
language objects are always exposed as wrapper objects that Java code
can work with, e.g. implementing java.util.Map (similar to
ScriptObjectMirror).

We are not exposing implementation-internal classes but instead have this language-agnostic Value interface abstraction. Can you share your code snippet?
