How can I check the commit message of AOSP
The Google Issuetracker offers an easy way to know the status of an issue: the sidebar.

Like any other issue tracking software, there are many different statuses an issue can be in.
To help clarify the status even more, there is a switch that tells whether or not an issue has been resolved and the changes are in "production" (ie. the current codebase of the project)

For your specific issue, the status is as follows:

Status
Won't Fix (Obsolete)
...
In Prod
(off)


This means that the issue hasn't been solved and will never be solved. It's probably not an issue anymore.
