I've updated the jar of hibernate and oracle jdbc driver but the problem still bothers me. Could you please help me for that?

It has been resolved by setting the property statement cache size to 0 (10 default) in datasource configuration page.
However, it seems that doing this will have a trade off on performance. What's more, someone said that using an updated JDBC driver will be also helpful but it failed to work. Could you please give me some other advice?
