It does not list the "default" for each release. However it does state
"The JAVA_HOME is the way to choose which JDK is to be used.".
Of course each product can override that. Domino tends to hardcode the
desired java version. And even if Domino supports some version of
java_home they will often will not run without the desired JVM loaded.
It's a stupid prereq check they do.
Here is a test I did:
savlicpgm ... jdk6 stuff to a save file
dltlicpgm ... jdk6 stuff
... oh crud
rstlicpgm ... jdk6 stuff
rinse, lather, repeat.
JDK6 doesn't run on 7.3 (but you know that)
jdk6 support ends Dec 2017 (this year!) for 7.2 and 7.1
If you cannot find jdk7 or 8 on your 7.1 media you can download them from
ESS. They came out later and do not appear on physical media even if you
order new media, respins or resaves, etc.
For what it's worth, your vendors suck. This shouldn't be an issue. They
should do more to say "7.3 will work fine, provided you are running our
release such and such or higher. You may have to change this ...
(environment variable, application setting, etc)"

...if apps start failing at V7R3, and 3rd party vendor cannot produce a
timely fix.

7.3 has been out long enough it should no longer be a cross your fingers
kind of thing.
