Coverage decreased (-0.02%) to 84.75% when pulling a30b659 on TheRealHaui:execute-Unit-Tests-parallel-with-Maven into 19e1b02 on apache:master.

Obviously, coveralls makes any kind of mistake measuring the coverage due to the fact that I've not edited any code.

Coveralls seems to be sensitive on which of the several JDKs we build with on Travis finishes first. Don't worry, this seems to be normal.

Your change is for the IT profile tests which aren't run on a regular basis. Each of these surefire instances will run the tests of a single class only. There won't be any difference between running them parallel "per class" or not in parallel at all.

As these tests are resource hogs - file system and memory in particular - they wouldn't be good candidates for running in parallel anyway.

For "normal" tests we inherit the settings from Commons Parent,

TBH I don't know whether jacoco would be compatible with a parallel execution of tests.

You're right the change is for the *IT tests.
Was sure I made the change for the normal Unit Tests ...

However, I've tested the change on my local machine excessively and didn't encounter any problems.

Thought this might be a good idea to incorporate.
However ... / Anyway it wouldn't have been in any way a great improvement.

Thank you for your reply.
I close the pull request.
