 Can't install openjdk20

 Making a long history short, I upgraded my system to Sequoia, so I did a
 ports migration that failed, I had to uninstall and reinstall Mac Ports
 and Xcode CLI tools because some ports were failing at build stage. This
 issue was fixed with re-installations but I cant install OpenJDK 20, when
 I had it installed with my previous system version just with Xcode CLI
 tools.

 sudo port -d install openjdk20
