`gradle test` is now failing with tons of IllegalArgumentException errors

[jzacsh]

This could be a non-issue if it turns out this is something wrong on my local setup, but I'm finding gradle test is no longer passing for me.

test failure

$ gradle test

just filed this really so I could answer my own question, for posterity, as I'm sure this will happen to someone else. (took me a couple hours of head-scratching to resolve).

solution: I was accidentally on a machine with jdk17. Installing jdk11 fixed my problem and everything's passing again.
