> if an outer query.iterate() calls within an iteration step a query.list() the connection is closed and the next outer iteration step causes:
> org.hibernate.exception.JDBCConnectionException: could not get next iterator result
> 	at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:97)
> 	at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66)
> 	at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:52)
> 	at org.hibernate.impl.IteratorImpl.next(IteratorImpl.java:156)
> the exception is only thrown if there is no transaction!
> (works fine if done within an transaction)
> call hierarchy:
> QueryImpl.list()
> -> SessionImpl.list(String query, QueryParameters queryParameters)
> -> afterOperation(success); // within finally block
> -> JDBCContext.afterNontransactionalQuery( success )
> -> ConnectionManager.afterTransaction()
> -> ConnectionManager.aggressiveRelease() // within if ( isAfterTransactionRelease() ) {
> -> ConnectionManager.closeConnection()
