@Convert не работает с Hibernate и QueryDSL

У меня есть таблица Incidencia со столбцом CHAR (1 байт) visiblemovil. В этом столбце есть 2 возможных значения: «S» или «N» (да/нет, si/no на испанском языке), которые я хочу преобразовать в boolean с помощью аннотации @Convert. Это мой код:

Конвертер:

@Converter
public class SiNoToBooleanConverter implements AttributeConverter<Boolean, String> {

    @Override
    public String convertToDatabaseColumn(Boolean aBoolean) {
        return aBoolean ? "S" : "N";
    }

    @Override
    public Boolean convertToEntityAttribute(String s) {
        return "S".equals(s);
    }
}

Объект:

@FilterDef(name = "PREGINCIDENCIA_FILTRO_FECHA", parameters = @ParamDef(name = "ultimaFechaSinc", type = "date"))
@Entity
public class Incidencia {

    private List<Incidenciapreguntas> preguntasList;

    private Integer codincidencia;

    private String descripcion;

    private Double horasfinalizacion;

    @Convert(converter = SiNoToBooleanConverter.class)
    private Boolean visiblemovil;

    private boolean tieneDocumentacion;

    @Id
    @Column(name = "CODINCIDENCIA")
    public Integer getCodincidencia() {
        return codincidencia;
    }

    public void setCodincidencia(Integer codincidencia) {
        this.codincidencia = codincidencia;
    }

    @Basic
    @Column(name = "DESCRIPCION")
    public String getDescripcion() {
        return descripcion;
    }

    public void setDescripcion(String descripcion) {
        this.descripcion = descripcion;
    }

    @OneToMany(mappedBy = "incidencia")
    @Filter(name = "PREGINCIDENCIA_FILTRO_FECHA", condition = "FMODIFICACION > :ultimaFechaSinc OR FMODIFICACION IS NULL")
    public List<Incidenciapreguntas> getPreguntasList() {
        return preguntasList;
    }

    public void setPreguntasList(List<Incidenciapreguntas> preguntasList) {
        this.preguntasList = preguntasList;
    }

    @Transient
    public boolean isTieneDocumentacion() {
        return tieneDocumentacion;
    }

    public void setTieneDocumentacion(boolean tieneDocumentacion) {
        this.tieneDocumentacion = tieneDocumentacion;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        Incidencia that = (Incidencia) o;

        if (codincidencia != null ? !codincidencia.equals(that.codincidencia) : that.codincidencia != null)
            return false;
        if (descripcion != null ? !descripcion.equals(that.descripcion) : that.descripcion != null) return false;
        return true;
    }

    @Override
    public int hashCode() {
        int result = codincidencia != null ? codincidencia.hashCode() : 0;
        result = 31 * result + (descripcion != null ? descripcion.hashCode() : 0);
        return result;
    }

    @Basic
    @Column(name = "HORASFINALIZACION")
    public Double getHorasfinalizacion() {
        return horasfinalizacion;
    }

    public void setHorasfinalizacion(Double horasfinalizacion) {
        this.horasfinalizacion = horasfinalizacion;
    }

//    @Basic
    @Column(name = "VISIBLEMOVIL")
    public Boolean getVisiblemovil() {
        return visiblemovil;
    }

    public void setVisiblemovil(Boolean visiblemovil) {
        this.visiblemovil = visiblemovil;
    }
}

Когда я выполняю оператор SELECT (с QueryDSL), я получаю эту ошибку:

org.hibernate.exception.GenericJDBCException: Fail to convert to internal representation
