AW: [17u]: GHA update: Use xcode 12.4. for macos-x64

[Doerr, Martin]

Hi,

I think this makes a lot of sense.

JDK 17 has XCode 12.4 as official requirement from the beginning (Oracle):
https://wiki.openjdk.org/display/Build/Supported+Build+Platforms

I think XCode 11 should no longer be used.
E.g., Apple requires 12 for App Store apps since 2021:
“Starting April 2021, all iOS and iPadOS apps submitted to the App Store must be built with Xcode 12 and the iOS 14 SDK.”
https://developer.apple.com/news/?id=itpt8dkc

Best regards,
Martin

Betreff: [17u]: GHA update: Use xcode 12.4. for macos-x64
Hi,

I would like to propose to update the compiler
used in GHA for macos-x64 from xcode 11.7 to xcode 12.4.

We already build macos-aarch64 with this compiler.
jdk21u uses xcode 12.5.1 in the GHA.
At SAP, we build with xcode 13 for jdk17, so this is tested already.

I think it is beneficial to have the same compiler for both
macos builds, and to be closer to jdk21.
Also, I assume more people are building with recent compilers
than with xcode 11 on mac.

Best regards,
  Goetz
