failed to install rJ in Mac OS Big Sur

The compilation of rj on Mac OS Big Sur is failing because JavaVM is deprecated (https://stackoverflow.com/questions/64844595/javacpp-builds-failing-on-macos-after-xcode-12-2-update-due-to-missing-javavm-fr).
I've made multiple attempts, including downgrading XCode 12 to 11 without success.
Here is a printout of the compilation:
