Confluence throws /rest/analytics/1.0/publish/bulk for events when Analytics is Disabled

2015-02-12 15:03:11,742 WARN [ajp-bio-8009-exec-1503] [analytics.client.browser.PublisherResource] apply BrowserEvent property values should not be Collections or Maps. name=user-menu-link-content.user-item.clicked, properties={data={id=logout-link}}

Similar issue to JRA-41593

Expected behavior
REST request should no longer be send to $URL/rest/analytics/1.0/publish/bulk when the Analytics is disabled ( Confluence Administration >> Analytics).
Note that the plugin is not disabled

Workaround
Disable Analytics Client Plugin from Manage add-ons -> System add-ons
