Hi Nick,
<div><br>
</div>
<div>We also discuss design issues on the amber spec experts list. We have not discussed this feature for a while though, for the reasons that Angelos listed. (Summary: We want to offer withers for all classes, so we need to get that story clear in our minds
so that we don’t make a decision for record classes that could get in the way.)</div>
<div><br>
</div>
<div>Cheers,</div>

<div>
<div>Hi Amber Team.<br>
</div>
<div><br>
</div>
<div>I'm currently checking out what could be finalized in java 25 and noticed that the "Derived record creation" JEP (<a rel="noopener noreferrer" href="https://openjdk.org/jeps/468">https://openjdk.org/jeps/468</a>) hasn't been updated since last year.<br>
</div>
<div><br>
</div>
<div>Is there any information available on the current state of this JEP or is it likely to be worked on in the near future? The feature would be very convenient in many cases.<br>
</div>
<div><br>
</div>
<div>Best regards,</div>
<div>Nick Hensel</div>
