Fix coverage report submission failure

[cogmission]

Failure due to erroneous error during the "2nd build" for test coverage. Coveralls plugin instruments classes and something there is causing a test which passes the first pass of the build, to fail.

Wrote message to JaCoCo Google group for help (5/ 8/ 2015). Waiting for answer...

Tried different settings in POM file - no successful combination. There is a known bug with the Surefire Plugin in Java 8 where memory needs to be added to the process using "argLine" property. The JaCoCo advice is that that "argLine" has to be declared as a property and the ${property} then added to the argLine parameter of the Surefire plugin - but that didn't work for me. So I'm still investigating.
