* This test checks if the transparent linked data caching works, based on an ldclient offline provider. It will try

* Available system properties:
* <ul>
* <li>PostgreSQL:
* <ul>
* <li>postgresql.url, e.g. jdbc:postgresql://localhost:5433/kiwitest?prepareThreshold=3</li>
* <li>postgresql.user (default: lmf)</li>
* <li>postgresql.pass (default: lmf)</li>
* </ul>
* </li>
* <li>MySQL:
* <ul>
* <li>mysql.url, e.g. jdbc:mysql://localhost:3306/kiwitest?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull</li>
* <li>mysql.user (default: lmf)</li>
* <li>mysql.pass (default: lmf</li>
* </ul>
* </li>
* <li>H2:
* <ul>
* <li>h2.url, e.g. jdbc:h2:mem;MVCC=true;DB_CLOSE_ON_EXIT=FALSE;DB_CLOSE_DELAY=10</li>
