> Hi team,
>
> This is a preview fix for the JFR-related crash - maybe the comment in this patch should be polished.
> TIL that complex problems often result from seemingly negligible changes :-)
> I need to cautiously test this change, though it seems no harm, to guarantee that it is safe and to ensure the problem is gone so please stay a little tuned.
>

> Update:
>
> 1. Overnight JFR testing reveals no error, seems fixed.
> 2. `test/hotspot/jtreg` on the board reveals no error until now - still testing, but I think it is safe.

> Thanks,
