Hi all,

I've received email from Naoto (jdk-updates Reviewer), but it wasn't delivered because he hadn't subscribed jdk-update-dev.
I share message from him:

I reviewed the following 11u backport of the fix to 8242283, and it looks good to me.


I cannot reply directly on jdk-updates-dev as I am not subscribing to it.
