  <p>Here is the relevant section of my pom file:</p>
  
  <pre><code>&lt;plugin&gt;
    &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
    &lt;artifactId&gt;maven-surefire-report-plugin&lt;/artifactId&gt;
    &lt;version&gt;2.8/version&gt;
    &lt;configuration&gt;
      &lt;argLine&gt;-Xmx512m&lt;/argLine&gt;
    &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Switching back to version 2.7.2 results in no error.  Anyone knows more about this?  Thanks.</p>
