RFR: 8297912: Redo 8252584 with the proper approval

[Julian Waters]

[8252584](https://bugs.openjdk.org/browse/JDK-8252584) was integrated too early due to a mistake on my part, we should redo it and go through the proper approval process this time

(The changes in this commit are exactly identical to 8252584)
