[hibernate-issues] [Hibernate-JIRA] Created: (EJB-300) create-drop with c3p0 causes SQLException

create-drop with c3p0 causes SQLException ----------------------------------------- Key: EJB-300 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-300 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.2.1 Environment: hibernate-entitymanager 3.2.1.ga, c3p0 0.9.0, and postgreSQL 8.1.8 or hsqldb 1.8.7 Reporter: Chris Redekop Attachments: c3p0Test.tar.gz In the attached test application, an EntityManagerFactory is created and then closed. Closing the EMF causes line 801 of org.hibernate.impl.SessionFactoryImpl to call getConnectionProvider().close(), which eventually results in c3p0's PooledDataSource being closed. Line 808 of org.hibernate.impl.SessionFactoryImpl the calls schemaExport.drop(), which attempts to acquire a connection from the data source and causes the following SQLException. java.sql.SQLException: com.mchange.v2.c3p0.PoolBackedDataSource@fced4 [ connectionPoolDataSource -> com.mchange.v2.c3p0.WrapperConnectionPoolDataSource@9505f [ acquireIncrement -> 1, acquireRetryAttempts -> 30, acquireRetryDelay -> 1000, autoCommitOnClose -> false, automaticTestTable -> null, breakAfterAcquireFailure -> false, checkoutTimeout -> 0, connectionTesterClassName -> com.mchange.v2.c3p0.impl.DefaultConnectionTester, factoryClassLocation -> null, forceIgnoreUnresolvedTransactions -> false, identityToken -> 9505f, idleConnectionTestPeriod -> 100, initialPoolSize -> 10, maxIdleTime -> 100, maxPoolSize -> 100, maxStatements -> 0, maxStatementsPerConnection -> 0, minPoolSize -> 10, nestedDataSource -> com.mchange.v2.c3p0.DriverManagerDataSource@80cac9 [ description -> null, driverClass -> null, factoryClassLocation -> null, identityToken -> 80cac9, jdbcUrl -> jdbc:hsqldb:., properties -> {user=******, password=******, autocommit=true, release_mode=auto} ], preferredTestQuery -> null, propertyCycle -> 300, testConnectionOnCheckin -> false, testConnectionOnCheckout -> false, usesTraditionalReflectiveProxies -> false ], factoryClassLocation -> null, identityToken -> fced4, numHelperThreads -> 3 ] has been closed() -- you can no longer use it. This exception is swallowed so it does not cause a test error, but it does appear in the console output. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
