在一次交易中我运行
delete from OdpObjectScheduleEntity e where e.id = 956101
然后，在另一个事务中（并且日志显示它是在上一个事务提交之后启动的）我试图保留一个id为956101的新OdpObjectScheduleEntity，但是有例外：
Caused by: <openjpa-2.2.0-r422266:1244990 nonfatal store error> org.apache.openjpa.persistence.EntityExistsException: An object of type "ru.focusmedia.odp.server.datastore.jpa.entity.OdpObjectScheduleEntity" with oid "956101" already exists in this context; another cannot be persisted.
