_I am not a reviewer; I maintain `java-17-openjdk` in `RHEL` so I try to review `rfr`-labelled pull requests for `jdk17u-dev`, time-permitting._

This change seems safe and like a correct optimization that should improve performance.  (It would have been nice if there were some performance analysis submitted with the original pull request that could have been re-run on 17.)
