Java 8 or 10?

[abazlinton]

The intro notes assume students likely have Java 10. And apparently most of them in E24 had it (not clear how / why). But the script forces 8. My laptop has 8. So need to investigate what's best.

I see no reason not to go for 10 over 8. All the Spring stuff works well with 10.

What else do we need to check?

[CraigMorton]

If we're moving on from 8 it should probably be to version 11 as it is the next LTS version and therefore the next real version that big project would feasibly switch to after version 8.

11 adds support for var for inferable type declarations and intelliJ will tell the students about this even if we don't.

homebrew has been on 11 since 25 Sep -

Homebrew/homebrew-cask@f1fecfe#diff-6149815b24e8a7b72a9bd0e438920500

So we can just remove

tap "caskroom/versions"
cask "java8"

And go back to

cask "java"

Though we might want to force 11? As people have a habit of always going for latest (homebrew could be updated to 12). And we should maybe stick with LTS.
