[2.2.2-java] duplicated list entries view for Lists. @repeat helper is wrong

With play 2.2.2 and the project samples/java/forms, in the route http://localhost:9000/contacts if you try to click in INSERT without filling any field, the view is refreshed and it shows the corresponding "Required field" error with more PROFILES than the ones created.

The same sample run using play-2.2.1 do not have this problem. 

I don't know if the issue is in the controller side with parsing List of objects, or in the view side, with the Form object.
