Interceptor for generic bean is not invoked

The following code does not work in Wildfly 8.1.0 CR. I'm getting exception: javax.persistence.TransactionRequiredException. I looks like the Weld issue as the stack trace does not contain Transactional interceptor invocation.

@Transactional
public static class Parent<E> {
protected EntityManager em;

public void create(E entity)

{ em.persist(entity); }

}

@Transactional
public static class Child extends Parent<EndEntity> {
@Override
public void create(EndEntity entity)

{ super.create(entity); }

}

then I invoking create() method in submitEntity():

public class EndEntityController {
@Inject
private Child child;

private Parent<EndEntity> parent()

{ return child; }

protected void submitEntity(EndEntity entity)

{ EndEntity endEntity = new EndEntity(); parent().create(endEntity); }

}

When the Parent class is not generic then the code above works.
