Kettle version:5.4.0-130 报错，这是什么原因？

Question

Kettle version:5.4.0-130 在跑job时偶发性报错，频率不高，后面自己就好了，以下是报错原因：
An error occurred reading job[xxx] from the reppository
Unable to load job entry of type 'trans' from the repository for id_jobentry=19063
Couldn't get row from result set
Unable to get value 'Integer(38)' from database reslutset,index 0
invalid column type:getLong not implemented for class oracle.jdbc.driver.T4CClobAccessor。

这些报错是什么原因导致的呀？
