The strange thing about annotations is that they are not inherited:

Class A { 
        @Inject 
        void method1(arg) {...}; 
} 

ClassB extends ClassA { 
        void method1(arg) {...}; 
} 

Attempt to inject ClassB won't trigger method1 as it is considered to be non-injectable. (There are tests for this in the JSR on the dependency injection and the same logic is used for other Java annotations.)
