Instead of showing N/A, it is now show missing. Output is still like above in the description.


jlink --module-path /Library/Java/JavaVirtualMachines/jdk-25.jdk/Contents/Home/jmods --add-modules java.base --output macos25
Error: jlink build N/A-26-internal-adhoc.hjen.JDK-8347831-2026-03-17 does not match target java.base build missing
