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 at fced4 [ connectionPoolDataSource -> com.mchange.v2.c3p0.WrapperConnectionPoolDataSource at 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 at 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.
