your changes look good, but you still use the new, backport bug id
8170873. Please update them to use the initial bug id 8170873.
There's also no need to create a bug for a backport manually. Once you
push a change with the original bug ID to the 8u-dev repositroy, a new
downport issue will be automatically created for you.
Once you've updated the webrevs and they are approved for 8u I can
sponsor the change for you.
