negative.code: [NOTE]
  Code using strings to identify properties will cause exceptions during runtime if the string contains a typo or if the name of the setter and getter methods have been changed without also updating the string.
  
  //todo change to new JSR303 support
  
  Bindings created based on a property name will automatically use JSR 303 Bean Validation annotations from the bean class if a Bean Validation implementation is available.
  Constraints defined for properties in the bean will work in the same way as if configured when the binding is created.
