Right. So that’s the minefield, no? If you download from Oracle, it’s like Photoshop from Adobe. If you download from Amazon, it’s like gcc. But it’s the same software: near invisible difference.
Are you a huge enterprise system that has to be able to call someone on some national holiday at 2AM? If no, then just do whatever you want - I don’t understand running to Amazon, when you can just do `apt install openjdk`, but whatever. There is way too much fuss around this non-issue. It’s the exact same software plus-minus a few bytes.
So that’s why you shouldn’t download from Oracle.
