code: @Nullable
    public static InputStream getInputStream (@Nonnull @Nonempty final String sPath)
    {
      final URL aURL = URLHelper.getClassPathURL (sPath);
      return _getInputStream (sPath, aURL, (ClassLoader) null);
    }
docs: Get the input stream for the specified path using automatic class loader
  handling. 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>
  
  @param sPath
  The path to be resolved. May neither be <code>null</code> nor empty.
  @return <code>null</code> if the path could not be resolved.
