Suppress warning in log when opening a non published document in the CMS

When I open a document in the CMS that is not published or configured to be shown on any channel, the following warning is logged:

[INFO] [talledLocalContainer] 30.12.2013 17:50:02 WARN http-bio-8080-exec-6 [DefaultHstLinkCreator$HstLinkResolver.resolveAllCanonicals:634] There is no Mount available that is suited to linkrewrite '/content/documents/[REDACTED]'. Return empty list for canonicalLinks..

This should at the most be an INFO, warnings indicate that something is wrong with the system and that need to have admins act on them.
