Interceptor for generic method with generic implementation is not invoked

XMLWordPrintable

      public interface BaseService<T> {
    void setSomething(T param);

    T getSomething();
}

public abstract class BaseServiceImpl<T> implements BaseService<T> {
    @Override
    public void setSomething(T param) {
    }

    @Override
    public T getSomething() {
        return null;
    }
}

public interface SpecialService extends BaseService<String> {
    @Override
    // for declaring some special annotations
    void setSomething(String param);

    @Override
    String getSomething();
}

@SomeInterceptorBinding
public class ManagedSpecialServiceImpl extends BaseServiceImpl<String> implements SpecialService {
}

@Stateless
@Local(SpecialService.class)
@SomeInterceptorBinding
public class EJBSpecialServiceImpl extends BaseServiceImpl<String> implements SpecialService {
}
      1. getSomething() - interceptor is not invoked at all.
      2. Injecting ManagedSpecialServiceImpl as SpecialService - for setSomethig() interceptor is not invoked, moreover setSomethig(Sting) of Weld proxy is bridge method of ManagedSpecialServiceImpl that direct call BaseServiceImpl#setSomethig(Object), so in BaseServiceImpl#setSomethig(Object) we have this = Weld proxy.
      3. Not reproduced by attached testcase, but in my application, for EJB injection interceptor for setSomethig() also is not invoked.
