Yes, parent().create(endEntity) is not intercepted. The reason is that Weld does not intercept bridge methods. If you call parent().create(endEntity) a similar synthetic bridge method created by compiler is invoked:

public class Child extends Parent<EndEntity> {
  public void create(Object entity) {
          create((EndEntity) entity);
  }
}

The following code snippet should work:

protected void submitEntity(EndEntity entity) {
  child.create(new EndEntity());
}
