ADDITIONAL SYSTEM INFORMATION :
macOS 10.14.6 18G9323 x86_64
Xcode 11.3.1 11C505
openjdk17, openjdk21

A DESCRIPTION OF THE PROBLEM :
JDK-8266242 fix for openjdk22 support for macOS 11.00 and later introducing build failure regression on earlier openjdk versions that still support building on macOS 10.12 - 10.15.

New if {} clause added to src/java.desktop/macosx/native/libawt_lwawt/awt/CGraphicsDevice.m includes identifier not defined in the macOS SDKs prior to version 11.00.

...
static BOOL isValidDisplayMode(CGDisplayModeRef mode) {
    // Workaround for apple bug FB13261205, since it only affects arm based macs
    // and arm support started with macOS 11 ignore the workaround for previous versions
    if (@available(macOS 11, *)) {
        if (architecture == -1) {
            architecture = [[NSRunningApplication currentApplication] executableArchitecture];
        }
        if (architecture == NSBundleExecutableArchitectureARM64) {
            return (CGDisplayModeGetPixelWidth(mode) >= 800);
        }
    }
    return (1 < CGDisplayModeGetWidth(mode) && 1 < CGDisplayModeGetHeight(mode));
}
...

The @availability directive included does not prevent the compiler from checking the enclosed code symbols are defined. Some mechanism/directive is needed to prevent this code section from causing a fatal build error.

REGRESSION : Last worked in version 11.0.24

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
bash configure
make images

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Successful build

CUSTOMER SUBMITTED WORKAROUND :
Can build successfully when #if guard is added to enclose the new code block, viz. (e.g. for openjdk17, almost identical patch applies to openjdk21):
