Porque a Injeção nesta classe não funciona?

Boa noite,

Por gentileza, não estou conseguindo realizar a injeção nesta classe, alguém poderia explicar? Não é possível realizar a injeção com classes que estendem "LazyDataModel" ou outras classes especificas?

Obs: A StackTrace apresentada no console segue abaixo, após a classe!

Grato!

        return dao.listaTodosPaginada(inicio, quantidade, "titulo", titulo);

    }
