Can not inject primitive values from property file using @Value annotation into servlet [SPR-8574]

I am not able to inject primitive values from property file into servlet. Complete sample code can be found here: https://github.com/lukas-vlcek/SpringValueAnnotationTest

In a nutshell:

1. I setup annotation driven config mode using <context:annotation-config />
2. I read property file <util:properties id="values" location="WEB-INF/inject.properties" />
3. Then in init() method of each servlet I call SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this, config.getServletContext());
4. Injection in servlet using @Autowired works fine but using @Value does not. More specifically see https://github.com/lukas-vlcek/SpringValueAnnotationTest/blob/master/src/main/java/org/test/springframework/inject/Bar.java Injecting using @Value annotation fails in this servlet.

Besides Bar servlet there two other servlets that work fine, these are Foo and Lorem servlets. I created these two working servlets to verify that @Value annotation works fine when not used directly on servlet (that is the case for Lorem) and in Foo servlet I show that the Properties object is loaded correctly using @Autowired annotation.

So the question is: is it possible to have primitive values from property file directly injected into servlet?

Good catch! We had too strong an assertion in there which I've relaxed accordingly. Fixed for 3.0.6 as well as 3.1 RC1.
