    Description

      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.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
