We talked about this before.

I decided not to use @implNote because it makes it easier to keep the source
in sync with the standalone version that's still built with an older JDK
(and javadoc).

It probably would've been better to word this differently so that it's clear
the location of the file is an implementation detail that depends on the the
JDK implementation, but at this point I think we've reached the point of
diminishing returns and it's time to just get this done.
