We have several Maven 3 multi-module projects running in Jenkins, having the "incremental build" checkbox enabled, which works like a charm.

What's not quite working as expected is the RSS feed for failed builds (/rssFailed). As intented, it reports modules having build failures. But it also reports all modules which were actually not built due to the "incremental build" feature.
The result is, that I get thousands of useless "not built" messages in the feed per day and the "real" build failures just are not visible anymore, rendering the /rssFailed feed useless for me.

PS:
Previous versions of Jenkins reported not built modules as "?" (see issue 11013).

PS2:
I'm not sure, if "core" is the correct component for this bug.
I took it because it's a mandatory field and I didn't find a better component...
