3.4版本中运行平台提供的任务归档功能，oracle数据库保存如下：

 Caused by: com.justep.exception.BusinessException: 编码: JUSTEP150039; 提示: 执行sql: delete from SA_Task where sFlowID in (select sFlowID from  (select sFlowID from SA_Task where  sKindID=? and (sStatusID=? or sStatusID=?) and sActualFinishTime>=?  and sActualFinishTime<=?  and version=? ) as t_tmp), binds: [tkProcessInstance, tesAborted, tesFinished, 2016-06-06, 2016-06-08, -1]出错

把下面的classes解压放到\runtime\BusinessServer\WEB-INF下,然后重启tomcat服务

3.5正式版中已经解决了这个问题
