title: NullPointer in log during first connection to database
body: <p>I get a <code>NullPointerException</code> on the console of my tomcat at my first connection to the database with <code>createEntityManager()</code>. I am using:</p>
  
  <ul>
  <li>apache tomcat 8.0.24</li>
  <li>eclipselink 2.6.1-RC1 (indirectly used by JPA)</li>
  <li>sqlite jdbc 3.8.10.1</li>
  </ul>
  
  <p>The log message is the following:</p>
  
  <pre><code>[EL Warning]: connection: 2015-08-21 16:01:51.569--java.lang.NullPointerException

  <p>My application seems to work fine - do I have to care about the <strong>warning</strong> about the <em>NullPointerException</em>? Or do I have to care about the <strong>info</strong>?</p>

  <p><strong>EDIT:</strong>
  Thanks to help of @baumato and the setting <code>&lt;property name="eclipselink.target-database" value="Database" /&gt;</code>the info about <em>Not able to detect...</em> doesn't show up any more. The detailed NullPointerException now is:</p>
