If you pull the latest ``HikariConfigurationUtil`` from the HikariCP ``dev`` branch, the H2 hack should no longer be necessary.  We also added code to pull additional default properties from ``hibernate.connection.*`` into our configuration:

```java
copyProperty(AvailableSettings.ISOLATION, props, "transactionIsolation", hikariProps);
copyProperty(AvailableSettings.AUTOCOMMIT, props, "autoCommit", hikariProps);
copyProperty(AvailableSettings.DRIVER, props, "driverClassName", hikariProps);
copyProperty(AvailableSettings.URL, props, "jdbcUrl", hikariProps);
copyProperty(AvailableSettings.USER, props, "username", hikariProps);
copyProperty(AvailableSettings.PASS, props, "password", hikariProps);
```
Are there additional properties that we should be pulling over?
