Stephen Pickett commented on HHH-2694:
--------------------------------------

Has this fix been confirmed? I've recently started getting this error again. Am still looking in to it to see if it's caused by something else that I've done but would be interested to see if anyone else still has the issue?

> 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.
