Comment (by sambthompson):

 Temporary patch PR submitted for openjdk17 and openjdk21. openjdk11 not
 affected as the ​JDK-8266242 backport was only applied to the
 openjdk11-oracle version upstream.

 Have also reported to upstream (including the patch) and am awaiting the
 issue of a report ID or follow-up questions.

 Further review of [https://openjdk.org/groups/build/doc/building.html
 Oracle's build instructions] suggests building with less than Xcode 13 is
 not supported, so a possibility the report will be rejected and the
 patches won't be temporary (although hopefully considered minor enough to
 accept):

 Notable comments:
 > It is recommended that you use at least macOS 13 (Ventura) and Xcode 14,
 but earlier versions may also work.
 ...
 > The oldest supported version of Xcode is 13.0.
