将Spring从3.2.0.RELEASE更新为3.2.1.RELEASE后出现以下错误：

java.lang.IllegalArgumentException: The source to convert from must be an instance of @org.hibernate.validator.constraints.NotEmpty @javax.validation.constraints.Size @javax.validation.constraints.Pattern java.lang.String; instead it was a ru.mystamps.web.model.ActivateAccountForm

[skip]

模型声明：

@FieldsMismatch(first = "login", second = "password")
public class ActivateAccountForm implements ActivateAccountDto {                                    
     @Size(max = ValidationRules.LOGIN_MAX_LENGTH)
    private String login;

    ...
}

控制器：

@RequestMapping(value = Url.ACTIVATE_ACCOUNT_PAGE, method = RequestMethod.POST)                 
public String processActivationForm(@Valid ActivateAccountForm form, BindingResult result) {
    ...
}

在这种情况下我做错了什么？

这听起来像是一个潜在的错误，但我无法复制它。您能否提供有关https://jira.springsource.org/browse/SPR-10243
