While the patch is fairly recent, it does not come with elevated risk, as it just skips the optimization in the case where the alternative is compiler crash.

Hi @shipilev, sorry to bother you but I see that since this PR was merged, jdk-21.0.8+9 was released, but I don't see the corresponding commit in that tag. I feel like I'm missing something but shouldn't it have been included in it?

Thanks for your help!
