When I am trying to read an entity from DB I am getting the following exception.

java.sql.SQLException: Result set already closed
at weblogic.jdbc.wrapper.ResultSet.checkResultSet(ResultSet.java:100)
at weblogic.jdbc.wrapper.ResultSet.preInvocationHandler(ResultSet.java:56)
at weblogic.jdbc.wrapper.ResultSet_oracle_jdbc_driver_OracleResultSetImpl.next(Unknown Source)

at org.hibernate.loader.Loader.loadEntity(Loader.java:1860)

I tried to figure out problem from hibernate source code.
I observed that closeStatements() in AbstractBatcher(org.hibernate.jdbc) is causing this problem.

Actually if the read operation is non-transactional it closes all the opened resultsets. I think this is not a correct behaviour.

It shouldn't close the sibling resultsets. It should close only the corresponding result set on which query has been executed.
