JPA 2.0 空值在刷新操作时从映射的超类继承的字段

我有以下层次结构

@MappedSuperclass
public class MensajeErrorBase{
@Enumerated(EnumType.STRING)
@Column(name = "SEVERIDAD", nullable = false, length = 50)
protected EnumSeveridadMensaje severidad;
//...
}
@Entity
@Table(name = "TRA_INGRE_IDENTI_MSJ")
public class IngresoPorIdentificarMsg extends MensajeErrorBase implements    Serializable, MensajeMonitoreo {
private static final long serialVersionUID = -8722933693750515329L;
@EmbeddedId
protected IngresoPorIdentificarMsgPK pk;
//...
}

以及我执行 crud 操作的跨 ejb。在另一个名为 ServicioProceso 的 ejb 中，我有以下方法：

private <T extends MensajeErrorBase> void guardarMensajesError(Class<T> claseEntidad, Serializable pk, List<T> listaMensajes,
                DatoSesionAud dsa) {
            try {
                MensajeMonitoreo msjMonitoreo = (MensajeMonitoreo) claseEntidad.newInstance();
                if (msjMonitoreo.getClaseMsjParam() == null) {
                    throw new RuntimeException(excepcionNosePropago(ServicioProceso.class, "guardarMensajesError",
                            "No estan configurados los metodos que retornan las clases de parametros en la clase de Mensajes Base"));
                }
                for (MensajeErrorBase mensajeErrorBase : listaMensajes) {
                    msjMonitoreo = (MensajeMonitoreo) mensajeErrorBase;
                    msjMonitoreo.setClavePrimaria((Serializable) BeansUtil.deepClone(pk));
                    super.insertSecuencia(msjMonitoreo, dsa);
                    List<MensajeErrorParamBase> listaMensajesParam = ((MensajeMonitoreo) mensajeErrorBase).getParametros();
                    for (int i = 1; i <= listaMensajesParam.size(); i++) {
                        MensajeMonitoreoParam msjMonitoreoParam = (MensajeMonitoreoParam) listaMensajesParam.get(i - 1);
                        msjMonitoreoParam.setClavePrimaria((Serializable) BeansUtil.deepClone(msjMonitoreo.getPk()), i);
                        super.insert(msjMonitoreoParam, dsa);
                        List<MensajeErrorParamParamBase> listaMensajesParamParam =
                                ((MensajeMonitoreoParam) listaMensajesParam.get(i - 1)).getParametros();
                        for (int j = 1; j <= listaMensajesParamParam.size(); j++) {
                            MensajeMonitoreoParamParam msjMonitoreoParamParam =
                                    (MensajeMonitoreoParamParam) listaMensajesParamParam.get(j - 1);
                            msjMonitoreoParamParam.setClavePrimaria((Serializable) BeansUtil.deepClone(msjMonitoreoParam.getPk()), j);
                            super.insert(msjMonitoreoParamParam, dsa);
                        }
                    }
                    super.flush();
                }
            } catch (InstantiationException | IllegalAccessException e) {
                LoggerUtil.runtimeException(e, ServicioProceso.class);
                throw new RuntimeException(excepcionNosePropago(ServicioProceso.class, "guardarMensajesError", e));
            }
        }

其中行：

 super.insertSecuencia(msjMonitoreo, dsa);

调用执行 crud 操作的 EJB 并发送对象 msjMonitoreo，其中包含来自映射超类和子类设置的所有数据。但在同花顺调用中，我得到以下异常：

当我调试时，所有字段都设置了 de 相应的值。调试显示已设置所有字段。我的服务器运行在 WebSphere Application Server (Full( 8.5.5.0 上。但是当我部署到 Liberty WebSphere 时，它可以正常工作

这不是

双重persistence.xml它是一个玻璃鱼虫：

https://github.com/javaee/glassfish/issues/16164

我不得不禁用编织：

<properties>
  <!-- Documentation https://www.eclipse.org/eclipselink/documentation/2.5/concepts/app_dev007.htm says its 'eclipse.weaving', but examples say its 'eclipselink.weaving'. Great. -->
  <property name="eclipselink.weaving" value="false"/>
  <property name="eclipse.weaving" value="false"/>
</properties>

我仍然不知道会发生什么，但我发现了问题：我有两个持久性.xml una 在我的耳朵应用程序中打包的库中，另一个在 ejb 模块中。所以我删除了 de ejb 模块上的那个，并将其持久性单元放在库的同一文件中。并且工作正常。我仍然不知道为什么它在自由服务器上工作正常，而在 IBM WAS 8.5 上失败。谢谢大家的帮助。
