When I use immutable form, I found validation behavior on the immutable form is not same as on the mutable form.
Please see attached images.
On the mutable form, validation is completely executed even if type conversion failed.
But on the immutable form, validation is not executed.
Please try my sample on github (https://github.com/MasatoshiTada/spring-mvc-form-sample).

Affects: 5.1 RC2
