Hey, sorry if it's not the right place for this, but I felt like I could add some more information to this bug.

I've been having this issue locally when trying to migrate some native code to Java 21+. I can even reproduce it on Java 22 / 23 when native code is throwing an `Access Violation (C0000005)`.

Did we have confirmation that the issue was properly fixed for all cases with that commit ?

Here's my WinDbg output on Java 23 (same for 21/22):

That native code is working fine for Java 8 / 17 btw.
