Review Comment:
No, in Maven the type `Version` can be parsed only within session (as
session is used to choose schema). RTInfo participates in places like `mvn -v`,
where there is no session nor should be session at all. So it would be check or
egg situation. RTInfo is good as is, all it should do is expose String version,
and let anyone interested in it possibly parse/compare/whatever.
