GenericConversionService.convert() throws IllegalArgumentException after updating to Spring 3.2.1

After updating Spring from 3.2.0.RELEASE to 3.2.1.RELEASE I've got following error:

[skip]
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

Model declaration:

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

    ...
}

Controller:

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

What I have doing wrong in this case?

This sounds like a potential bug but I am having trouble replicating it. Could you provide some more information on https://jira.springsource.org/browse/SPR-10243
