IT test coverage is 0% using Jacoco in SONAR - integration-testing

Question

I am using:
SONAR v.3.2 (it has jacoco)
Maven 3.0.4
Followed "http://johndobie.blogspot.in/2012/05/easy-unit-and-integration-code-coverage.html#comment-form" to get separate code coverage for unit & IT tests. But IT test coverage is shown as 0%.
It is generating separate jacoco-unit.exec (44kb) & jacoco-it.exec (14kb), but coverage is only shown for unit tests on SONAR.
Logs shows as:

You can check our sample projects here: https://github.com/SonarSource/sonar-examples/tree/master/projects/languages/java/code-coverage/combined%20ut-it
You'll find examples of projects having both unit and integration test coverage reported thanks to JaCoCo.
