'How to create a mac universal binary with bundled JRE?

I am creating a JAVA desktop app for Mac computers, using jpackage to bundle the desired JRE into the app and finally shipping a .app to the customers.

With the new m1 apple arm silicon computers I do not want to create different apps for each processor architecture with the right JRE (intel & arm) but create one single universal binary app that launches the Intel JRE on Intel computers and the Arm JRE on Arm computers. I know this is possible somehow.

I tried to create two .apps and use the lipo tool from the mac command line, but this doesn't really work.

Any suggestions how to proceed?

I took the Zulu Intel and arm JRE (not JDK) builds and lipo'ed the binaries. You can download JRE 17 universal here:

Tested on intel and arm macOS 11 Big Sur.
