If that implicitly happens on CI, because there is never a pre-existing Java installation there, then I guess that’s could be ok, although I personally think it’s good to have explicitly set fallback versions.

Yes, it would need to be a dynamic default, taking into account the OS 
version, build_arch, and java.version in order to pick a JDK port that 
will work.

I don't understand why having individual ports set their own fallback 
version would be considered better in general, since it doesn't actually 
guarantee that a specific JDK will be present. The portgroup's behaviour 
is to use any installed JDK that meets the requirement given in 
java.version. Ports that need a specific JDK need to explicitly declare 
a dependency on it either way.
