@VinInn:
At the beginning of the Jenkins unit tests there seems to be an error (shown below). Does this error indicate a serious problem? Is it related to this PR?

+1

For #8628 349fe9d

Fix for Jenkins time-out.

The code changes are satisfactory, and Jenkins test results against baseline CMSSW_7_5_X_2015-04-02-1100 show no problems, other than the unit test error message mentioned above that is probably not significant.
