"SettingsFactory" no longer checks for presence of "supportsGetGeneratedKeys" before calling it ----------------------------------------------------------------------------------------------- Key: HHH-5017 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5017 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Steve Perkins A number of users are experiencing Hibernate failures when using various combinations of Oracle JDBC driver versions and JDK versions. A sample stacktrace is below: Initial SessionFactory Creaion Failed.java.lang.AbstractMethodError: oracle.jdbc.driver.OracleDatabaseMetaData.supportsGetGeneratedKeys()Z Exception in thread "main" java.lang.ExceptionInInitializerError at HibernateUtil.buildSessionFactory(HibernateUtil.java:27) at HibernateUtil.<clinit>(HibernateUtil.java:17) at EvenManager.createAndStoreEvent(EvenManager.java:33) at EvenManager.main(EvenManager.java:26) Caused by: java.lang.AbstractMethodError: oracle.jdbc.driver.OracleDatabaseMetaData.supportsGetGeneratedKeys()Z at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:123) at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2119) at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2115) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1339) at HibernateUtil.buildSessionFactory(HibernateUtil.java:23) ... 3 more The basic issue is that the "supportsGetGeneratedKeys" method does not exist on the "oracle.jdbc.driver.OracleDatabaseMetaData" JDBC driver class for many versions of Oracle. Even if you use the "hibernate.jdbc.use_get_generated_keys" config property, Hibernate still makes a call to that method and execution still fails. Up until version 3.2.7.GA of Hibernate, the code checked for the presence of "supportsGetGeneratedKeys" prior to calling it. The problem emerged with version 3.3.2.GA, where now Hibernate just calls the method without first verifying that it exists. If there was no functional reason for removing this safety-check, can we please re-insert it to prevent such failures?
