[Gerhard Petracek]

hi gunnar,

@constructor:
we tried something similar in a project. it worked but it introduced a big
performance issue and we had to remove it again.

>
> public class Foo {
>
>  @Valid
>  public Foo() {
>
>  }

> Here @Valid would trigger a validation of the newly instantiated Foo
> object (whether to use @Valid or another annotation still needs to be
> discussed). Any thoughts?
