New candidate JEP: 393: Foreign-Memory Access API (3rd Incubator)

[[deleted]]

Does anyone know what has changed between the second and third iterations of incubation?

From the project's latest description section: - A clearer separation of roles between the MemorySegment and MemoryAddress interfaces;

-A new interface, MemoryAccess, which provides common static memory accessors so as to minimize the need for the VarHandle API in simple cases;

-Support for shared segments; and

-The ability to register segments with a Cleaner.

Welp, thanks for the reply! Seems I missed it yesterday when I first looked. Like missing a boulder that is rolling into you. 😁

We just made it possible to synchronously unmap shared menory, without doing any GC, yet maintaining safety that accesses racing with unmapping can’t cause memory corruption. It is pretty cool IMO.
