Review comment:
I think that just showing there's no `ArrayIndexOutOfBoundsException` is
probably a bit weak, since we're explicitly setting the contents of both arrays
in the test, so we know that exception isn't possible here. Asserting that the
method is behaving as expected for the given conditions (not calling
`removeIdWithSerial()` for buckets that correspond to an `ILLEGAL_SERIAL`
value) would make for a more meaningful test.
