title: Why hikaricp gives me Method not found: setUrl at startup?
body: <p>I am developing a GWT app without Maven nor Spring, but I want to use HikariCP as my connection pool so I downloaded HikariCP-2.2.4.jar from Maven's Central Repository along with pgjdbc-ng-0.3-complete.jar for my postgresql driver; finally I have updated my hibernate libraries from 4.1 to 4.3.</p>
  
  <p>I am using the following HikariCP Properties on my hibernate.cfg.xml</p>
  
  <pre><code>&lt;property name="hibernate.connection.provider_class"&gt;com.zaxxer.hikari.hibernate.HikariConnectionProvider&lt;/property&gt;
  &lt;property name="hibernate.hikari.dataSourceClassName"&gt;com.impossibl.postgres.jdbc.PGDataSource&lt;/property&gt;
  &lt;property name="hibernate.hikari.dataSource.user"&gt;user&lt;/property&gt;
  &lt;property name="hibernate.hikari.dataSource.password"&gt;pass&lt;/property&gt;
  &lt;property name="hibernate.hikari.maximumPoolSize"&gt;10&lt;/property&gt;
  &lt;property name="hibernate.hikari.dataSource.url"&gt;jdbc:postgresql://localhost:5432/db&lt;/property&gt;
  </code></pre>
  
  <p>Now, when i start the application it gives me the next Exception:</p>
