Your original Gist says: "This works for the current JDK head, JDK 23 and JDK 21. So I would assume
<br>
that it affects all JDKs that include the Shenandoah GC at the moment of writing."<br>
<br>
Could you double-check the issue reproduces on JDK 21 for you? I found a bug that affects JDK 25:<br>
<a href="https://bugs.openjdk.org/browse/JDK-8350580?focusedId=14756096#comment-14756096">

<br>
...and my prospective fix resolves JDK 25 crash. But the reproducer runs fine on current jdk21u-dev.<br>
<br>
Thanks,<br>
