Snapshot dependencies with sources/test classifier are not considered 'changing'

Hi
There is an issue https://issues.gradle.org/browse/GRADLE-2175 which is marked as resolved, but me and @hexucheng (see last comments) are able to reproduce it.
I’m on 2.14.1 and Artifactory.
Please reopen the 2175 bug, same issue here : Artifact cache - sources artifact update
Thanks
