Angular Js post date Bad Request in Java Spring mvc

In Java Spring MVC project, I post an object to a @RestController and the object I post has an date property. If I remove this property, the post works successfully. But with the date property, it returns a 400 bad request. In the dto the Date is java.util.Date

Method in controller:

@RequestMapping(value = "/users/createPetition", method = RequestMethod.POST)
public @ResponseBody PetitionDTO addPetition(@RequestBody PetitionRequestDTO petitionDto, Model model) {   ...

PetitionRequestDTO

public class PetitionRequestDTO {

private Long userId;

private Long categoryId;

private String title;

private String description;

private Date initialDate;

private String address; //getters setters

The angular js call

if ($scope.petitionForm.$valid) {
        $http.post(getCompletePath("users/createPetition"), JSON.stringify($scope.newPetition))
        .success(function (petition) {

        }).error(function (data, status, headers, config) {

        });

In the js the date has the next value: Thu Mar 19 2015 00:00:00 GMT-0300 (Argentina Standard Time)

The complete json is:

"{"selectedCategory":{"id":3,"name":"Plomero","description":"Plomeria"},"name":"aaa","title":"bbb","description":"ccc","initialDate":"2015-03-19T03:00:00.000Z","address":"asd","categoryId":3}"
