Plone.caching: myriades of Intercepted exceptions after Plone 4.0 -> 4.3 migration

Plone Support Add-on Development
1

Migrating from Plone 4.0 to Plone 4.3.3. Standard Plone migration worked without error.
Rendering standard pages with standard views spills tons of the following Intercepted exceptions on the console as lone is plone.caching is enabled in the Plone control panel.

Bug or feature?

It's part of how plone.caching works (I forget the details). In new
Zope2 instances 'Intercepted' is included in the default list of
exceptions ignored by error_log. So my guess is there is a missing
upgrade step to add it.

Thanks, this explains it, so nothing to worry about.
