get resource is null
<p>I have an <code>@Test</code> method with invocationCount=3.</p>

<p>Each time this method is run, there is a call for preparing some doc into another method.</p>

<p>All it's working GREAT when the <code>@Test</code> is run for the 1st time.</p>

<p>The doc is succesfully found and loaded:</p>

<pre><code>final DocumentRegistryResource documentRegistryResource = 
    RestClientFactory.getInstance().createDocumentRegistryResource(
        getUserRestAuth());
final File importFile = new File(
    this.getClass().getResource("/documents-template-test.xml").getFile());
</code></pre>

<p>BUT, at the 2nd and 3rd invocation, i receive a null exception:</p>

<pre><code>this.getClass().getResource("/documents-template-test.xml")
</code></pre>

<p>is no longer found.</p>

<p>Can anyone explain me WHY? The original file is on the same place, nothing was moved
during the 1st time invocation...</p>
