I've verified all cases I can think of manually, but would like to defer the creation of a sanity test to a follow-up RFE to allow time to think through and discussing how to best go about that (do we need to verify in depth, can we reuse some existing test etc..)

I think it’s better to include a good test case in this REF, especially since object archiving is a new feature.

Well, I'm not sure about "good", but I have a test case I've tinkered with that simply tests that identity of Integer.valueOf behaves as expected w.r.t. Object identity around the break-off point. I'm pondering if we need to inspect the archived values more deeply, but perhaps it's good enough as a sanity test for now:

WDYT?
