I used this guide to refresh my JAX-RS knowledge. Unfortunately, when I went to apply that, I was getting a 500 error back in my client but there was nothing useful in the server logs (even with debug tracing).

It turned out to be a dumb mistake on my part (ArrayOutOfBoundsException), but is there a suggested way for configuring a root exception handler so that future mistakes like that would at least get logged?

I ended up following the advice at https://stackoverflow.com/a/19680115/161022 to register an ExceptionMapper and inserted a log statement there. If that is the recommended approach, it might be nice to add something like that to this guide so that anyone starting from here will have unhandled exceptions logged for them. Let me know if I'm missing something!
