3 years ago If you have an alternative solution, I’d love to know it. We couldn’t figure one out even after consulting with engineers at Apple.

Looking in the Console there are errors like:
Sandbox: java(87457) System Policy: deny(1) file-read-data /Users/mcphee/Downloads which support the idea that the OS is blocking these accesses.
Weirdly, if I start it from the command line (./jes.sh) the problem doesn't exist and it can find things in "Downloads" and "Documents". This makes me wonder if the suggestion to "simply disable" new versions of Java actually doesn't completely work. That's a pretty icky workaround for beginning students, especially in a course that's supposed to be friendly for non-computer-nerds. 😢 (& looking at the console, it appears that the same version of Java from the same place is being started whether I double-click the snake or run it from the command line. Not at all clear what the difference might be.)
I tried giving the Java 8 java full disk access, but that didn't fix/change anything, which seems odd.
This sounds like it's perhaps related to #128.
