This change fixes the name collision preventing build.

Thanks for your comments @dholmes-ora, @GoeLin, and @andrew-m-leonard.

I wanted to get the ball rolling on this issue since it is currently blocking Adoptium's build. They are eager to have it fixed in time for their next GA mid January. I don't believe the regular merge from 11u-dev into 11u would happen in time.

Given the time crunch, I was hoping to solicit the assistance of someone with more authority in the OpenJDK community to move the process along if possible. If this is not possible, I'm happy to proceed as listed in the [document linked above](https://wiki.openjdk.java.net/display/JDKUpdates/How+to+contribute+a+fix)
