Error on upgrade

Got the following on recent upgrade from 2.7 to 2.8

Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/site/public_html/sites/all/modules/advagg/advagg_js_compress/advagg_js_compress.advagg.inc on line 453

Parse error: syntax error, unexpected T_STRING in /home/site/public_html/sites/all/modules/advagg/advagg_js_compress/advagg_js_compress.advagg.inc on line 453

Looks like a typo here

function advagg_js_compress_jsqueeze(&$contents, $log_errors = TRUE) {
  $contents_before = $contents;
  // Only include jshrink.inc if the Patchwork\JSqueeze class doesn't exist. 
  if (!class_exists('Patchwork\JSqueeze')) {                   <<<<<<<--------------
    include drupal_get_path('module', 'advagg_js_compress') . '/jsqueeze.inc';
    $nesting_level = ini_get('xdebug.max_nesting_level');
    if (!empty($nesting_level) && $nesting_level < 200) {
      ini_set('xdebug.max_nesting_level', 200);
    }
  }
