Too many warnings in log: "Cannot find web resource module for: …"

Some warnings are appearing in Confluence log:

2013-02-12 20:43:31,590 WARN [http-8686-68] [atlassian.plugin.webresource.DefaultResourceDependencyResolver] resolveDependencies Cannot find web resource module for: com.atlassian.analytics.analytics-client:js-events
 -- url: /plugins/servlet/notifications-miniview | userName: xxxx | referer: http://confluence/display/RFPF/Errors+and+Warnings

Basically this bug is related to this CONF-25603, but we see now this same warning in Confluence 4.3.6 and 4.3.7.

Workaround

This message does not typically indicate an actual problem with the system. You can hide it by going to "Logging & Profiling" under the Administration settings, and adding a configuration for:

• com.atlassian.plugin.webresource – level ERROR.

This will hide all "WARN" level messages from this area of the system.
