My understanding is that each 'java.vm.specification.version' which is the JDK
version won't change within this major release. Especially with Oracle's 6
month release cycle it is very unlikely that one will see 12.1 as a last update
for JDK 12. New feature will be in n+1 where n in a major version. LTS versions
won't receive new features in most cases and wil stay with patch versions. But
even if they do, they will immediate stop suppporting n.y-0.1 and require you
to run n.y.

That is by I would keep everything from 11 as integers and not as fractions.
