Error in converter for Selectmanycheckbox

Question

I am making a Java web application and came across a problem in the converter to be used in selectmanycheckbox. The converter I made was this:

@FacesConverter(forClass = Indicacao.class)
public class IndicacaoConverter implements Converter {

    // @Inject
    private Procedimentos procedimentos;

    public IndicacaoConverter() {
        procedimentos = CDIServiceLocator.getBean(Procedimentos.class);
    }

    @Override
    public Object getAsObject(FacesContext context, UIComponent component, String value) {
        Indicacao retorno = null;

        if (value != null) {
            Long id = new Long(value);
            retorno = procedimentos.porId(id);
        }

        return retorno;
    }

    @Override
    public String getAsString(FacesContext context, UIComponent component, Object value) {
        if (value != null) {
            Indicacao indicacao = (Indicacao) value;
            return indicacao.getId() == null ? null : indicacao.getId().toString();
        }

        return "";
    }

}

The mistake....

It’s pointing to that line...

        Long id = new Long(value);
