title: Error java.lang.OutOfMemoryError: GC overhead limit exceeded
body: <p>I get this error message as I execute my <code>JUnit</code> tests:</p>
  <pre><code>java.lang.OutOfMemoryError: GC overhead limit exceeded
  </code></pre>
  <p>I know what an <code>OutOfMemoryError</code> is, but what does GC overhead limit mean? How can I solve this?</p>
