Какова связь между полем "SYSTEM_PROPERTIES_MODE_ENVIRONMENT" и PropertyPlaceHolderConfigurer?

Я использую spring 3.0.6-RELEASE для базовой формы на основе webapp и запускаю следующую ошибку при запуске с PropertyPlaceHolderConfigurer. Не уверен, что причиной этого было вложение свойства pre-mvc3 было сделано через beans, а теперь с помощью аннотации, и он выглядит довольно прямолинейно, по крайней мере, из документов/других сообщений.

Однако исключение во время запуска сервера tomcat жалуется на org.springframework.core.ConstantException: Поле 'SYSTEM_PROPERTIES_MODE_ENVIRONMENT' не найдено в классе [org.springframework.beans.factory.config.PropertyPlaceholderConfigurer]

Вот что я имею в spring -servlet.xml

<context:property-placeholder location="/WEB-INF/classes/spring.properties"/>

и мой класс контроллера

@Controller
@RequestMapping("/home")

public class HomeController {

    // @Resource(name="broomManager")
    @Autowired
    private broomManager broomManager;
    private @Value("${spring.broom.maxFileSize}") String inMemoryMaxFileSize;
    private @Value("${spring.broom.fileDestination}") String destFilePath;

..

spring.properties

broom.maxFileSize=100000
broom.fileDestination=/Users/foobar/broom/files/

Исключение при запуске
