JPA erro com metodo refresh?

Programação Java
,
#1

Estou com o seguinte erro, toda vez que chamo o metodo refresh do JPA da o seguinte erro: Estou usando JPA + Vraptor 4

public void recarrega(Produto produto){
   em.refresh(produto);	
}

vcs vao falar da linha no qual diz: Entity not managed, porém a classe ta certa, insere no banco normalmente ta tudo mapeado, pode ser um detalhe, mais to o dia todo agarrado nisso!

Só da o problema com o refresh
