title: getClass().getClassLoader().getResourceAsStream() is caching the resource
body: <p>I have a resource (velocity template) which I'd like to be able to swap during development.  However, </p>
  
  <pre><code>getClass().getClassLoader().getResourceAsStream() 
  </code></pre>
  
  <p>seems to cache the template.  Is there a way to disable this besides using a file loader instead of the class loader?</p>
