JLS 5.1.7 has no provisions about the identity of these boxes: neither a guarantee they would be cached, nor a guarantee that they would _not_ be cached. JLS 5.1.7 note explicitly calls that out: "For other values, the rule disallows any assumptions about the identity of the boxed values on the programmer's part. This allows (but does not require) sharing of some or all of these references.".

That reassuring. Thanks for finding that in the spec! I think that removes the cancer.
