Drupal 8.x

Hello,

I am getting the following error after updating a code on a Dev instance on Acquia Cloud:

Error: syntax error, unexpected 'private' (T_PRIVATE) IN /mnt/gfs/ourfolder/livedev/vendor/symfony/dependency-injection/Compiler/AutowirePass.php, line 178

Will greatly appreciate your thoughts.
