Levan, that's already corrected under https://hibernate.atlassian.net/browse/HHH-8811 and will be in 4.3.1. Brett Meyer Red Hat, Hibernate ORM ----- Original Message ----- From: "Levan Tsinadze" <levantsinadze(a)gmail.com&gt; To: hibernate-dev(a)lists.jboss.org Sent: Tuesday, January 21, 2014 6:54:59 PM Subject: [hibernate-dev] Prepared statement for EAGER entity relations returning cursor not closed Hello everybody I found that after migrating from 4.2.8.Final to 4.3.0.Final, if I have several @OneToMany EAGER entity relations and select at least 500 rows I get ORA-01000: maximum open cursors exceeded JDBC exception for Oracle database (ojdbc 12.1.0.1) I think problem is in org.hibernate.loader.plan.exec.internal.AbstractLoadPlanBasedLoader.executeLoad method which calls (line 156, column 106) org.hibernate.engine.jdbc.internal.JdbcCoordinatorImpl.release(ResultSet resultSet, Statement statement) method and this last method closes only passed ResultSet, not Statement. I also found that in 4.2.7.SP1 in such case is called org.hibernate.engine.jdbc.internal.JdbcCoordinatorImpl.release(Statement statement) which closes as ResultSet as passed Statement.
