title: @DatabaseSetup unable to load data set
body: <p>I configured my test environment via java config. At my test I need some data upfront to run it, but when i run the test with the <code>@DatabaseSetup</code> annotation I always get the error </p>
  
  <pre><code>Unable to load dataset from "personTestData.xml" using class com.github.springtestdbunit.dataset.FlatXmlDataSetLoader
  </code></pre>
  
  <p>The file is located at <code>src/test/resources/personTestData.xml</code>. Out of curiosity I moved the file into the same package where the test itself is located, still the same error.</p>
  
  <p>I have spent countless hours searching the web for the error, no solution till now.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Components and version I use:</p>
  
  <pre><code>junit: 4.12
  hamcrest: 1.3
  springtestdbunit: 1.2.1
  dbunit: 2.5.0
  bonecp: 0.8.0
  hsqldb: 1.8.0.10
