Just looking at the issue it's coming from this code:

if ( ConnectionProvider.class.equals( unwrapType ) ||
                DriverManagerConnectionProviderImpl.class.isAssignableFrom( unwrapType ) ) {
            return (T) this;
        }
        else {
            throw new UnknownUnwrapTypeException( unwrapType );
        }

where unwrapType is javax.sql.DataSource.

Whilst I can't explain exactly what it is about your config that causes this I can suggest a fix.

Define a DriverManagerDataSource bean in your spring application context and then provide this as a property to your LocalSessionFactoryBean. Make sure you remove the datasource configuration from your Hibernate configuration file.
