Add macOS Intel build and fix mac code signing via jpackage - #65
Merged
Conversation
GitHub only offers Apple Silicon macOS runners for standard builds, so
add a macos-26-intel matrix entry to package.yml to also produce an
x64 build, alongside the existing arm64 one.
Switch the mac packaging profile from fvarrui/javapackager's mac
bundler to the JDK's own jpackage. javapackager's mac launcher
(universalJavaApplicationStub) is a shell script, not a Mach-O binary,
so rcodesign can't sign the resulting bundle ("Invalid magic number").
jpackage produces a real compiled launcher that both codesign and
rcodesign can sign correctly.
jpackage's runtime bundle also trips a known jpackage quirk (OpenJDK
JDK-8237490): Contents/runtime/Contents/Info.plist declares
libjli.dylib as CFBundleExecutable, causing it to be signed twice
(once as a nested bundle's main executable, once generically) which
notarization rejects. Strip CFBundleExecutable from that plist before
signing so libjli.dylib is only signed once.
