@cmsbuild can we have the jenkins run (as a matter of principle before signing off)?

Identical to #4801 but history fixed (I am to put -1 to #4801).
See the comments in the other PR, there is also a description to the PR
in the comments (I failed to make developers put it in the actual PR description)
Jenkins for this new PR are as expected as well (for 25adaa6).

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_2_X IBs unless changes (tests are also fine).
