Hello,

Thank you for reaching out!

I'm pretty sure that the amber-dev mailing list is not the correct place
for this type of question. This topic usually goes on at the following
mailing list instead. I've CC'd it for you. I would also encourage you to
remove amber-dev from your CC when responding to me, or anyone else on this
thread.

discuss at openjdk.org

To answer your question, this is a very common request, and the biggest
answer is definitely still the backwards compatibility problem. But tbh,
the question I have for you is this -- is it such a big cost to call the
o1.equals(o2) method instead of using ==? And if you want to handle nulls
too, you can import java.util.Objects (that class is full of useful static
utility methods) and then just say Objects.equals(o1, o2) instead. I am
pretty sure that that exact method was created in response to your exact
question.

I understand it might be inconvenient, but making a change like you
suggested would be very disruptive for very little benefit. All you would
gain from doing this would be a slightly better syntax for representing
object equality and a little more ease when it comes to teaching somebody
Java. Is that really worth the effort?

As for the class-file api, I'll CC them so that someone can fact check me.
Assuming I'm not wrong (no one responds to that point specifically), I
would also drop that mailing list from your CC when responding.

The purpose of the Class-File API was to build and transform class files.
So that seems unrelated to what you want. You want to repurpose old syntax,
but syntax stops being relevant after compilation, and it is these compiled
class files that the Class-File API deals in. If we tried to use that API
to handle class files created with the old syntax, then we would have a
migration and clarity problem, amongst much more.

Let us know if you have any more questions.

Thank you for your time!
David Alayachew

In fact, the discuss list is not appropriate for this type of question.
Per the list?s description [1]:

  This list is for general discussion about the OpenJDK Community,
  including proposals of new Projects and Groups.

  This is not a place to discuss specific technical proposals. For that,
  please use an appropriate area-specific mailing list.

  This is not a place to ask support questions. Please direct those to
  whoever provided your JDK build.

The OpenJDK Developers? Guide includes a list of area-specific mailing
lists [2], but there isn?t a list specifically for the Java programming
language.  Given that the charter of Project Amber [3] is to ?explore
and incubate smaller, productivity-oriented Java language features,?
the original poster?s choice of amber-dev was reasonable.

- Mark

Ok. Thanks for the heads up.
