SchemaUpdate closes shared ConnectionProvider --------------------------------------------- Key: HHH-1445 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1445 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1.2 Reporter: fdo Assignee: Steve Ebersole Fix For: 3.2.0.alpha1, 3.1.3 Summary of thread : http://forum.hibernate.org/viewtopic.php?p=2289756 - I have a standalone application, configured to use c3p0 as connection pool - when I first connect to the db, Hibernate updates the database using SchemaUpdate from SessionFactoryImpl. This schema update is created using the SchemaUpdate(cfg, settings) constructor [[this constructor didn't exist in Hibernate 3.0.5 but it does in 3.1.2]], which doesn't instantiate a new ConnectionProvider but uses the one from the settings - when SchemaUpdate is done, it closes the ConnectionProvider, which cannot be used afterwards - afterwards, when I try to do something on the database, it appears the (closed) connection provider from the settings is used and it explodes...
