docs: Get the input stream for the specified path using automatic class loader
  handling. If no class loader was specified in the constructor, the class
  loaders are iterated in the following order:
  <ol>
  <li>Default class loader (usually the context class loader)</li>
  <li>The class loader of this class</li>
  <li>The system class loader</li>
  </ol>
