Adicionar um item a uma lista relacionada Hibernate

Estou tentando adicionar um Veiculo para um ‘Cliente’ as entidades possuem uma relação OneToMany, onde um cliente pode ter varios veiculos.

Na minha pagina de pesquisa, estou enviando o id do cliente para a tela de “NOVO VEICULO”

<p:button outcome="/cliente/NovoVeiculo.xhtml" icon="ui-icon-plusthick" title="Novo Veiculo" > <f:param name="cliente" value="#{cliente.id}" /> </p:button> 

Na tela de novo, recebo o id pela URL

<f:metadata> <o:viewParam name="cliente" value="#{novoVeiculoBean.cliente}" /> </f:metadata>

Meu Bean

@Named @ViewScoped public class NovoVeiculoBean implements Serializable {      private static final long serialVersionUID = 1L;      private Cliente cliente;      private Veiculo veiculo;      @Inject     private VeiculoService veiculoService;      public NovoVeiculoBean() {         limpar();     }      public void limpar() {         veiculo = new Veiculo();     }      public void cadastrarCarro() {         this.veiculo.setCliente(this.cliente);         this.cliente.getVeiculo().add(this.veiculo);     }       public void updateVeiculo() {         cadastrarCarro();         this.veiculoService.salvarVeiculo(veiculo);          FacesUtil.addInforMessage("Cadastro realizado com sucesso!");     }      public Cliente getCliente() {         return cliente;     }      public void setCliente(Cliente cliente) {         this.cliente = cliente;     }      public Veiculo getVeiculo() {         return veiculo;     }      public void setVeiculo(Veiculo veiculo) {         this.veiculo = veiculo;     }  } 

Porem quando tenho esse erro ao persistir
