Java program built on Ventura will not run on Monterey

Hello,

I have a Java app that I have built and bundled using:

  • Java 17 Temurin x64
  • JPackage
  • Fully signed

I have tested the created dmg and it runs without issues on Ventura with an M1. I have a customer using an Intel-i7 with Monterey who cannot run the program - the installer works. The error is "You can't open the application XXX because this application is not supported on this Mac".

I am not using XCode. My build is using ANT.

Is there a log somewhere that will give me more information about the exact error? Is this expected behaviour? The JDK I'm using is the x64 version, which should work with Intel.

Thanks!
