I was going to modify documentation in the separate JIRA: it's still difficult to me to express my thoughts in english.
So I have needed the approvement of the solution for a start.
Should I do it here, or separate JIRA is OK? Of couse it will be in 3.0.M2 already...
About tests. Np, will be pushed soon, although they will look as double check how Spring MVC works, because as I said this solution fully based on Spring MVC abilities.
Other comments will be addressed too.
