When running my installer on MacOS, it doesn’t detect the OpenJDK 21 installed by Sdkman so it downloads this internal file macos-amd64-21.0.1.tar.gz from my private webserver. That seems an issue too.

It extracts it and set the destination in a random folder like this one:

/var/folders/vb/wd0tzjrd0t9d7s32szf179tm0000gn/T/C2949B03-3FB4-4D8A-892F-E7AD7C2FC848-35063-000016F4FF276DC2/jre.bundle

when it tries to keep the installation an error is thrown:

I have run the debug_installer.sh and it has no issue, I guess is not doing the JRE step.

I expect that JDK is detected and, in case there is no JRE installed in the computer, to download the one in my private webserver and install it.
