Once ARQ-2042 was resolved, I rebuilt arquillian-persistence against the new arquillian-core
and ran into a problem where the database connection was being closed once the first test
in my class had finished. I see the same pattern in some of the integration tests so I don't
know what is different with my environment (other than openejb-embedded).

After a lot of debugging I finally narrowed the problem down to this change from Alpha6:

	private void createDatabaseConnection() {

		try {
			if (databaseConnectionProducer.get() != null
					&& !databaseConnectionProducer.get().getConnection().isClosed()) {
				closeDatabaseConnection();
			}

to Alpha7:

    private void createDatabaseConnection() {

		if (databaseConnectionProducer.get()== null) {
            configureDatabaseConnection();
        }

    }

    private void configureDatabaseConnection() {
        try {
