The latest Jquery update module (2.4) has a minor bug whereby it doesn't provide a minified version of certain ui js files
_sites/all/modules/contrib/jqueryupdate/replace/ui/ui/minified/jquery.effects.highlight.min.js?v=1.10.2
in
_/sites/all/modules/contrib/jqueryupdate/replace/ui/ui/minified
and therefore we will get 404 logs for these.
This is actually because the source files have changed their names from :
_/sites/all/modules/contrib/jqueryupdate/replace/ui/ui/minified/jquery.effects.highlight.js to
_/sites/all/modules/contrib/jqueryupdate/replace/ui/ui/jquery.ui.effect-highlight.js
There is some discussion on the issue queue about this. see https://www.drupal.org/node/2123973
