>   super(..) or this(..).  The statements cannot reference the instance
>   under construction, but they can initialize its fields.  Initializing
>   fields before invoking another constructor makes a class more reliable
>   when methods are overridden.  This is a preview language feature.

Hearing no objections, I’ve targeted this JEP to JDK 24.
